Live chat would be spammed with vulgar obsceneties all day every day whether it takes 5 or 10 new accounts per a$$hole. They will do it and ruin anything "we the good people" could find useful.
One glance at the IW forums and you will see how terrible it will get for the people on the end of live chat.
OR hey, can anybody ever remember a screaming angry 10 year old who lost in search so he just flips out?? haha
I think this would get horrible abused if implemented
The idea is amazing, though. Props mike
