Before a new user can post on the forums they must 1st change from the default icon, and then they must wait a week. After that week they can start making post, but they can not start threads. In order to start a thread they must have at least 100 post in other threads. After all that they can post one thread a week until they make 5 threads that are not flagged by at least 2 people or are locked. After they meet all that they can be considered real members and be allowed to do what they want.  
This is not all serious.
