I hate to post on a somewhat "dead" thread, but I didn't want to make a new thread either. I've been experiencing similar problems even though this account is at least a few years old... but then again, I have a low post count because I'm a bit of a lurker.
I think it might help to have not-yet approved posts in our list of posts with a little "awaiting moderation" note next to it. I just submitted a topic for the second time because I thought that my first one was either rejected for an unknown reason or because of an internet error (I know some websites have been acting funky since Sandy hit). Now I feel paranoid that I'm going to have both topics up in a few days and I'll look dumb/like a spammer. :/
