I don't know if you have already covered this in a previous post (if you did, sorry to ask again). I looked, but didn't find a post covering plotbunny posts specifically.
I just thought it might be nice to have a specific forum just for plotbunnies or story ideas that authors for some reason or another couldn't finish. You could also put challenges there too I guess. I noticed that challenges just go in whatever forum they fit into.
Would BI be interested in having a plotbunny/challenge forum? Or would it create more work for moderators? I don't want to cause trouble, I just thought it might make things easier and help inspire some writers.
I suppose you could even have a moderator check over the posts to make sure they're acceptable.
Sadly, I have no plotbunnies to add to a forum if one were made. I feel sorta bad asking for a forum when I don't even have anything to post in it.

So that was all I had to say, and if I'm totally wrong, don't feel bad to slap me. (I have a feeling you wont feel bad at all..I heard rumors of a noodle or something...it sounded really scary.)
Thank you for your time.
