I was thinking it would be a good idea to allow the OP of a thread delete it and not have to PM a mod to do so. I know there is a lot of for sale threads out there that could be cleaned up if the OP was able to remove their own threads by just deleting the OP of the thread. I myself have about 10 to 15 that could be removed. Also being able to change the title of the thread yourself I'm sure mods get lots of requests for that one.
Just a thought
