Why Minisinoo Doesn't Use Ratings
Just what it says.  A little essay on the rating system of fanfic and why you won't see me employ it.

Original Characters in Fanfic
Or, When is a Mary Sue not a Mary Sue?  What IS the difference between an original character and a 'Mary Sue'?  For that matter, what's a Mary Sue?  And why is there such suspicion in the fanfic community about original characters in fanfic?

Bren Keubler's Writing Rambles
Bren has things to say about fanfic and writing as well (similar to my "musings" above).

Macedon's The Craft of Writing
This went missing for a while when the old site it was on imploded, but I was able to locate it again recently.  Wonderful summary of basic dos and don'ts for beginning authors.

Resources for Writers (Unfit for Society)
This link goes off-site, but it references a whole lot of resources on how to write better.  I'd considered making something like this myself, but why re-invent the wheel?  Just go here.  Let me especially recommend, for grammar issues, the Elements of Style (of course) and Danger Mom's Handy-Dandy Grammar Guide.  And for stylistic issues, or how to write better prose, Holly Lisle's Forward Motion Writers' Pages, C.J. Cherryh's Writerisms and Other Sins, and The Official Kate Elliott Website's The Writing Life. The Mary Sue Litmus Test is great fun, too, by the way.
