Due to a mass of trolling, only established posters are able to post in non-newbie sections. You are considered "established" if you have spent 4 hours online and have made 5 posts.
If you have really good posts, you can post a request for preemptive whitelisting in the
appropriate topic.
Also:
- You must have made one post in order to send PMs.
- You need 10 posts to put a link in your signature.
Note that it may take up to 10 minutes for your PM or posting permissions to be granted.
I think 4 hours online is too much. I think that it should be 1 hour, maybe 2, but not more.
