Welcome.
If you can, you just now need to wait 4 hours (or be online 4 hours, don't remember) to get whitelisted.
You can only post in the Newbie and Local sub-forums till you have made one post and waited 4 hours. This post must be substantial: at least several sentences. The other two restrictions are you need 1 post to be able to send a PM and 10 posts to put a link in your sig.
