Ive often wished that the site had a instant messenger service. Myspace has one that only lets you talk to one person at a time. That would be fine. You wouldnt be able to monitor the conversations like in the forums, however, it would allow for free speaking, and arguments between virtual enemies wouldnt have to go on in public forums. Also I think it would be a great tool to facilitate intelligent conversation quickly.
