How prevent old threads from "falling off"

Some may have noticed that there are now so many new and old threads, that we have reached page 20. After page 20, all messages will begin to "fall off" and never to be seen again. There are two ways to prevent this.
1)Do some "spring cleaning". Delete stupid advertisement threads to make room for the new ones.
2)Creat and "Archives" forum by moving old threads there to make room for the new ones.

Either of the procedures will definately work, but since I have no power, I cannot do any more than bring attention to the issue. I personally like number one, but we need someone who will agree to do it. We must take action soon, or some of the greates threads of Entmoot will simply "disapear" if we don't.
