Maybe have like a Misc forum where you can just post anything, or could you just do that in the fun forum?
Chit Chat tends to be the place to put such things; what were you thinking of posting exactly? Fun & Games is more forum games, sharing online quiz scores and that sort of thing. We will be doing a major reshuffle of the sub-fourms in the near future (I think the techy people are working on it currently) so we'll have new sections for quite a lot of things; I'm not sure if Chit Chat and Fun & Games will be affected though. If you let us know what you planed on posting, we'll point you to the right forum
