I voted for 50 because I think that is enough, although I do think that 25 would be just fine if General discussion posts didn't count. Just taking the queue from other boards that I'm on. Many of them do not count chit-chat/general posts to post count. Therefore the posts that count towards your total aren't all bullshit irrelevant crap. I know some of you are proud of your 5000 posts, but 99% of them are from making quibs on useless general threads.
