Who needs anything else when there's Meebo? haha. You looking for alternatives in case ur Network admins starts blocking Meebo packets?
My MIS dept has blocked... iloveim msn2go e-buddy meebo Now, I'm using radiusIM which is so far behind meebo.
But typing on the phone is not that fun. I tried it once chatting with Chai and Peaz for about 1 hour. My hands were so sore after that..
