I've noticed, and received complaints that people are having trouble posting. We're going to try to figure out the problem, but my suggestion is that if you get the message that you aren't authorized to post, just go back, copy the post, refresh the page, and try to repost. It should work. As for avatars, if it doesn't let you, refresh, and try again. We'll try to sort out the problem shortly, thankes for your patience.
