I see your point souleman...I just noticed my first message and didn't mention security holes in IMs specifically...........I will edit that

I'm actually looking at all of them.
I know people are using ICQ, AIM and M$Messenger.

I know of many holes that come out....but I need good REASON to disallow their use.

As in, "Hello Manager, These programs are a threat to xxxxx corp. because of yyyyy. Hence I think we should discontinue the staff's ability to use such programs"
