(Sorry, guys. I've sent a warning to sloop about this already.)
Sloop: Believe it or not, I'm not going to take the time to go back and delete old posts just in case you were thinking of replying to them.
I think that's what you were asking for. If you were asking for the people who have stopped coming here to come back and delete their own old posts, I think that's even less likely.
Please don't bump very old topics. It's distracting and annoying to the active users watching for new topics.
