I know there is probably no way to do anything about it but I figure I'd ask. Is there any way I could get rid of old chats I sent on someone elses account? I should have kept it all "off the record" but didn't figure I'd get blackmaled later. Please let me know if any of you guys have an idea?

clikc on chat, flag the chat you want to delete, use the pull down and chose delete.. but what were you doing on another persons account..eh ?? :)-

you will need to be logged in with that "someone elses account" to do this!!

You can an only delete your copies, not the someone else's copies. It's the same as sending an email: you can't delete it once sent.
