It's all just part of noobie jail. If they weren't required to make 5 posts each / log in for 4 hours then this subforum would not be the way it is. But there would be other problems if newbie jail didn't exist. Do not question lord theymos and his implementations 
I thought the rules had been updated. I thought only 1 post was needed now, not 5.
