After posting, an account will need to be manually moved to an unrestricted group by a moderator, which should generally happen within hours. Until that happens, restrictions include needing to enter a captcha to post, lack of UBBCode (so quotes and URLs, etc, will remain in plain text), a longer delay between posts and no option have a profile picture or signature.
Repeated generic posts will be assumed to be spam, and the account will be deleted. There is no automated way to bypass the new user account restrictions based on post count.
"generally happen within hours"
Ok so when do I get rights to BBCode? I certainly joined more than a few hours ago.
Edit: ok I read the sticky post and sent a PM... heh.
