As a matter of fact I wish we could go back in an EDIT our posts like you can on most of the other boards I am familiar with. As for being "in a conversation with with another and say something you regret, you can't take it back," this is the Internet 2008, you CAN take something you said back and stop the hurt or even correct a typo or miss-spelling. The ability is there; why not use it?

Cheers,
Bill
