Feedback from New Editors
On the editing toolbar, if you click "Advanced" and then look for the word "Heading", and then select from the dropdown menu, it will give you the various heading titles automatically formatted. :)
Another great reference is at http://outreach.wikimedia.org/wiki/Bookshelf/Wikipedia (the top one includes a one-pager on wiki-markup.)
Thanks for the tip (although the PDF won't load-or maybe it just takes forever). What headings go where? Page titles, section titles, subsections, etc.?
