As in, I'm changing chat clients so I can reach out to more people than just Microsoft Messenger. There's nothing wrong with the application or the service, but in order to talk to more people, I've switched to Pidgin which means I can use my AIM, gTalk, and Messenger account all in one application.
For messenger, my user name is mspassport (@) robballen (dot) com
For AIM and Google Talk, it's robb (dot) allen (@) gmail (dot) com
If you're on another chat app, like Yahoo, let me know and I'll see how hard it is to hook that up as well.
