Replying to An Idea That Could End the Newb Issue

Okay, heres my idea that could end the newb problem. When a new user creates an account, they will only have posting acess to a new forum called the Newb Forum. the newbs will have the ability to see all other public forums but they will not be able to post there, so after either 100 posts in the Newb Forum or 10hrs activly online, they will be promoted to a normal user. This idea should fix the problem of newbs creating dumb threads or posting in threads that have been inactive for years.
