I'm hoping we can get the same math support that other SE sites (math.SE in particular) are making use of. Does anyone know how to enable this ?
Here's a test to see if the current system works by default: $t^2$
This discussion on meta.math appears to have a solution to the problem, and in fact Geoff Dalgas is one of our moderators too. Geoff, can we have math markup enabled for this site ?
Update: in the meantime, we can use John Gietzen's greasemonkey script directly (if you use firefox). I have it installed and can see the $t^2$ in the original question.
They use jsMath, but some people seem to prefer the newest MathJax, AFAIU. A good starting point may be this thread : add LaTeX support to Markdown/WMD
Hope this helps.
