Feedback from New Editors
I've had the exact same problem. It would be good if someone would tell us how to add a title, for pity's sake! I like that when you click the "I" for italic text, it gives you a prompt ''Italic text''. Perhaps wikimedia could add "Title" and "Sources" to this toolbar? It is very frustrating to flip back and forth from the wiki markup page to the article you're trying to work on.
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.?
