To follow up on http://meta.codereview.stackexchange.com/q/5017/9357Help spot deficiencies in our Help Center, let's collaboratively draft better Help Center pages.
For each Help Center page to be modified, post a Community Wiki "answer" containing the original text of the page. Please try to reproduce the markup as faithfully as you can. Then, everyone can start editing it! (Be sure not to edit your own post within the first five minutes, else your modifications will be incorporated into Rev 1.)
