Until recently (I'm not sure exactly when), at the top of every page was an "faq" button, and the page it led to had a list of basic help topics. Some of them were generic to SE, but some were specific to Math; most importantly "How do I ask a homework question" and "How do I use $\LaTeX$/Mathjax"?
As of now, the "faq" button has been replaced with one marked "help", which links to a page with a cooler layout and graphics, but which only seems to describe generic SE usage. https://math.stackexchange.com/faq leads to this "help" page as well.
These pages should be readily accessible to new users, since as we all know, inappropriate homework questions and improper formatting are a serious drag on the site. But now I can't even find them myself.
What's going on here?
