And Breezy said what I could have said about SPPf. (I'm a member there as well.) It's the same thing with BMGf. There's not even a sub-forum for authors to ask questions about writing, but there are reviewers for the stories posted there. People get out and review.
I'm going to start tonight by reviewing a story. Though I'm not going to be happy if I'm the only one reviewing.
The Archive houses the fics that won Fanfiction of the Month previously. But it, like the Revision Bin, is not in use.
