Kat - be REALLY careful with ICQ. I've been hearing increasing horror stories. Invisible mode is no guarantee - I've got mine on invis, and have been spammed a couple times, and have even had one guy who buzzed me out of the blue (I'm set to not accept messages from people not on my buddy list) and claimed he was just testing'a new toy he'd found'.

Until they patch the holes and release a new version, it is probably safest to keep it off unless you're actively expecting to talk to someone...
