I was wondering if vBulletin has any updates or extra hacks regarding the G-Talk chat similar to how it has for the AIM, Yahoo Messenger, and Skype clients to where you can add other people to your list or talk to people via G-Talk. If so it would be a great improvement. But if not, don't worry about it too much.
Keep up the good work,
Pavan
