As expected, not everything we are used to from SE works by default when installing Q2A as it is and creating a site. However there are some helpful plugins to improve the functionality of the site.
So this short post is to keep track of what is already installed or has been tested and what plugins would potentially be nice and useful to have.
Suggestions of useful plugins can be pointed out in the comments.
Already installed and tested:
Edit History
https://github.com/svivian/q2a-edit-history
This allows puts a link below each post to view the edit history. There is no roll back feature and they only plan to allow moderators to roll back in a future version. The link is a bit capricious, which may be related to the fact that there seems to be a
bug.
Q2A Markdown Editor LaTex
https://github.com/thibaultduponchelle/q2a-markdown-editor-latex
Certain things as for example the array environment
\begin{array}
\end{array}
Do not work for some reason, whereas when displaying the question on MathOverflow for example :-P, it works beautifully …
Maybe the “standard Markdown Editor together with a Java script for LaTex works better, as suggested by Dimension10 (?) …
Add an image upload button to the Markdown Editor
This works nicely, without solving the LaTex problems however …
Here is a stupid question with a nice image:
Comment voting
http://wiki.question2answer.org/doku.php/plugins/comment-voting
There appear no comment vote buttens for some reason, but the provider wisely said that it might not work as expected…
Q2A tagging tool
https://github.com/svivian/q2a-tagging-tools
Works nicely
Pinging @user
http://sourceforge.net/projects/scorchqaplugins/files/latest/download
This seems to have a bug
To be installed and tested as soon as possible
Q2A History
https://github.com/NoahY/q2a-history
Q2A Markdown Editor
https://github.com/svivian/q2a-markdown-editor
This needs to be complemented by a Mathjax Java script

Schrodinger's Cat Strikes Back 
I think I managed to understand the problem with the MarkDown + LaTeX.
I found out somewhere on http://www.MaThJaX.org that in an earlier version of MaThJaX, the commands like “\begin”, “\end” weren’t installed.
Probably, the MD+MJ editor used this old version of MaThJaX. This problem is also evident, on e.g. AskBot.
As for it working in the edit histories, my explanation is that the edit history plug-in has an intrinsic MaThJaX renderer which uses the latest CDN or file.
This problem can be fixed by using the standard MD editor with the image upload button.
The Markdown Editor with the image upload button works :-), however it does not solve the LaTex Problem…
Well, obviously the image upload won’t solve a LaTeX problem.
When you say it “works”, do you mean that an image can actually be uploaded (not just a link)/ ? If so, to which image host (Assuming it’s not the PostImage extension that you used) ?
The image is displayed directly in the post, you can either upload it from your computer or give a link, similar to how it works on SE. You can see an example in this blogpost, but dont laugh at my stupid test questions 😛
I have not looked at how and where the image is hosted …
Concerning the LaTex, I can test if it helps when I do exlusively this second +1 answer to this questions
http://www.question2answer.org/qa/1996/how-can-i-configure-q2a-to-support-mathtex-or-latex
and nothing else. Do work with the LaTex Markdown Editor we had to slightly change some scripts etc too …
Oh, that’s nice! But I still don’t get it, which image service does it use? It’s important to ensure that it doesn’t randomly destroy it’s images.
The second answer is the same as what I said, adding the CDN to the top of the page.
By the way, you don’t actually need to any major script-changing for that. It can be found in the administrator panel.
Maybe one could ask in the Q2A Forum about what image service the Plugin uses, in the Fucking Manual how to install it this is not explained
Concerning the LaTex, I have written these lines at the top if each page (Admin -> Layout)
MathJax.Hub.Config({ extensions: [“tex2jax.js”], jax: [“input/TeX”,”output/HTML-CSS”], tex2jax: {inlineMath: [[“$”,”$”],[“\\(“,”\\)”]]}, TeX: { extensions: [“AMSmath.js”,”AMSsymbols.js”]} });
and this at the Head of each page
The first one might be only needed by the LaTex Markdown-Editor however …
Not a plug – in, but a suggestion: If we are using the markdown editor, we could try using the
Courier Newfont instead.https://github.com/svivian/q2a-tagging-tools
http://wiki.question2answer.org/doku.php/plugins/comment-voting
Here’s a plug – in that allows one to *upload* an image (not just post a link) using a service called PostImage.Org.
http://blog.inventic.eu/2012/11/q2a-markdown-editor-with-file-upload/
…for free, by the way.
http://wiki.question2answer.org/doku.php/plugins/comment-ajax
Doesn’t make page reload once you post a comment. Comment appears spontaneously.
It has the disadvantage of people with bad internet connection (like me) not realising that their comment was not really submitted .
I just learnt that there is yet another reason for not enabling this.
See here: http://www.aiqus.com/questions/34067/aiqus-admin-added-support-for-latex-syntax-math-formulas
MaThJaX works on load an enabling AjAx would make it not reload.

Have you tested out the MJ-CDN+Ordinary MD Editour?.
Yep that is the last possibility to be tested 🙂
My technical friendly helper ( this user is maybe interested in the new site too http://physics.stackexchange.com/users/21123/a-friendly-helper), has found out, that the Markdown Editor with Latex swallows from time to time som characters, such to obtain “row breaks” in a matix one has to write /// instead o // for example. As the problem persists when using the ME with image upload button, I suspect that that one does the same and the probability is hight that the most simple one will do the same … He said he will investigat the issues with the Markdown Editors further 🙂
Conserning importing the TP data, my friendly technical helper managed to import the users, whereas importing the posts is still work in progress …
Ok, so that’s the problem. (It’s “\\”, not “\\\”, by the way)
It is important to ensure that it is correctly added, i.e. that “\\” is enough, since or else, the imported data dumps will not function well.
By the way, after quitting the installation of the data dump, I can see that the data dumps, once downloaded, are divided by site.
Oops, I mean it’s “\\”, not “//”.
Thinking about my recent MSO question and then reading this comment
http://meta.physics.stackexchange.com/questions/5122/i-leave-physics-se-this-is-my-good-bye-note#comment14802_5122f
my gut feeling is that the new site might become more important as a repository for Physics SE questions too, than we first thought. Since these questions have no other place to go (Astronomy and the Popular Science Area51 proposal could accept parts of them however) …
So it is good that the large data dump can be divided by site 😉
If Physics.SE is to fail, getting the individual data dump would be
much easier.

The in-built favouriting is not really bookmarking as you don’t get to track activity on it.

It seems that Phys.SE does not’ use the ordinary MaThJaX CDN, as you can see from the html of any Phys/.SE page.
MathJax.Hub.Config({"HTML-CSS": { preferredFont: "TeX", availableFonts: ["STIX","TeX"], linebreaks: { automatic:true }, EqnChunk: (MathJax.Hub.Browser.isMobile ? 10 : 50) },
tex2jax: { inlineMath: [ ["$", "$"], ["\\\\(","\\\\)"] ], displayMath: [ ["$$","$$"], ["\\[", "\\]"] ], processEscapes: true, ignoreClass: "tex2jax_ignore|dno" },
TeX: { noUndefined: { attributes: { mathcolor: "red", mathbackground: "#FFEEEE", mathsize: "90%" } }, Macros: { href: "{}" } },
messageStyle: "none"
});
If one does not use this, then inline maths will have to be entered as \(MATH-EXPRESSION-HOW-TO-SPELL-THAT\) instead of $MATH-EXPRESSION-H0W-TO-SPELL-THAT$.
I propose that we slightly modify that further as
MathJax.Hub.Config({"HTML-CSS": { preferredFont: "TeX", availableFonts: ["STIX","TeX"], linebreaks: { automatic:true }, EqnChunk: (MathJax.Hub.Browser.isMobile ? 10 : 50) },
tex2jax: { inlineMath: [ ["$", "$"], ["\\\\(","\\\\)"], ["##","##"] ], displayMath: [ ["$$","$$"], ["\\[", "\\]"] ], processEscapes: true, ignoreClass: "tex2jax_ignore|dno" },
TeX: { noUndefined: { attributes: { mathcolor: "red", mathbackground: "#FFEEEE", mathsize: "90%" } }, Macros: { href: "{}" } },
messageStyle: "none"
});
