Locked Topics

I think topics that are old, expired, or getting off topic should get locked scince there is really no other point in talking in that topic. if we get off topic we can just post a new topic of the thing we were getting off topic with lol, what do ya think? good idea?

The only reason i should lock is a topic, is if comeone had a question, and they found their answer, for right now all other topics remained open.
I would also lock a topic if There is no possible response to the main idea, or if I belive no one else needs to discuss this, incase anyone wants to argue my authority.
