Couple things real quick since I'm sick:
Yes, we plan to open new forums. If you know writers in a specific fandom who want feedback, please tell them to talk to me and we'll see about getting them established.
I'm against telling people to write stories JUST for this site. TFF should be a place for writers to pitch ideas and get real feedback before posting elsewhere so they don't have to beg for constructive feedback.
New features are something I'd really like to see and I'm generally open to suggestions. There's a limit on what I can do with icyboards' format, but that's no reason to stop thinking about it.
Content, though, is king. The big issue with TFF as it currently exists is that most of our primary boards are old fandoms, and what's still active is seeing talk instead of writing. So yeah, we need people writing for Harry Potter and Type-Moon, but we should be recruiting people interested in RWBY, the various MOBAs, Hero Academia and as always Pokemon.
So yeah actually daniel, I would like to see you do a monthly thing. Throw in some writing challenges and Iron Fic over the summer and recruitment and... well, at least we'll have fun.
