If you hadn't noticed, I haven't put together any of the things that I plan to yet for here ^_^. There are a bunch of worksheets and stuff that Ms. Fairchild made in the Sudden Fiction section, though, to tide you over, as well as the external links below...
Character Study - put together by Ms. Fairchild
Out_Lines LJ Community Archive
Creative Writing Forum - yes, this is a megatokyo forum, but it's one of my favorite 'net hangouts. And they despise fanfiction, so don't worry that it's going to be something mt-exclusive.
Articles, Hits and Tips on Writing - extensive collection on everything from memoirs and journals to ... everything. Yea, just go.
Teen Ink - a collection of writing contests
iUniverse - a place to self-publish
