Do you guys post your works to the RAAC?

Haven't yet.  Keep on planning to, though.

If so, when do you do this? After finishing
the whole thing, having edited it from useful
C&C, or do you send it in by installments
each time you finish the final version of
each part?

Well, my self-inflicted rule is this: If I can read the story/chapter 3
times in a row without making a change, then I say it's complete, and
ready to be posted.
