What features should we add to this site?

edit

I think William had already mentioned this, but adding support for jsMath / MathJax would be great.

edit (by evgeny): this page has instructions on enabling MathJax http://askbot.org/doc/mathjax.html, please take a look if you want to use math rendering on this site.

The markdown tips show up when composing a new question, but not when composing an answer--that would be useful. Along these lines, showing a list of all tags when composing a question could be inspirational when trying to think of good tags for the question.

I'm not sure if it's possible with Markdown, but it would be useful to have syntax highlighting for code blocks. Pygments appears to be the best choice for server-side highlighting in Python applications. Or would this be better to do here in the client?

This is really minor, but it would be convenient if the subscriptions email headers had a "from" entry to make email filtering a bit easier.

There is no "flag offensive" button for comments, only for answers and questions.

It would be nice if the profile page informed me of my daily quotas (voting/___ thresholds): both the threshold, and the amount left for the day. :-) My votes for today are consumed (I saw via the red pop-up).

A protocol for including a question and answer by the same person.

This site is a much better reference than the sage-support group. The questions are edited and refined and misguided answers move down the list (but remain there, just in case), and the search works (take that, google). So how about this becomes the place to share some tips with other users? But should we expose all the tip in the question or split it in two parts? And what should be done with the karma?

On sage-support, Karl mentioned the similar website mapleprimes. One thing I like there is that they have "posts" in addition to "questions":

MaplePrimes Posts are for sharing your experiences, techniques and opinions about Maple, MapleSim and related products, as well as general interests in math and computing.

Of course one can write a question and then give the post as its answer, but that seems a little silly (unless it's not possible to set up posts, in which case I'd be in favor of a FAQ item recommending precisely this strategy :).

Would it be possible to include optionally the entire (unformatted) content of new questions, answers, and comments in the subscription emails? And possibly for updates, the before and after versions or a simple diff of the changes?

edit: this should be working now, edited in the post so that you could see whether the feature works for you or not.

It would be nice if the "red envelope" messages didn't disappear completely after one view. Maybe they could be queued for auto-deletion (like voicemail), something configurable (say 7-14 days after first view.) Is it a performance or storage concern? Deletion or archival doesn't bother me either way, it just would be nice to see them for a few days (since sometimes it's hard to find the same message again if one thinks of another follow-up comment/Q/A).
