To combat some of the recent influx of spam we've gone to a moderated forum setup. Existing users most likely won't be impacted, but all new users should be moderated until then reach a set number of posts. I won't post what that value is for now.
Anyways, if you want to be unmoderated before that set number of posts, you can post a message here requesting that you be unmoderated, but you must post what the letters SCCA stand for, to prove that you might actually be legit. If you pass the test, you might just get unmoderated, no promises though.
