Alright so here's the deal. You have an IM you wanna share, you join and post it here. Simple enough right? =D Any medium is cool: yahoo, AIM, ICQ, MSN, ABC, BBQ, all of that. Text messages are fine as well.
What isn't cool is joining to ask people to IM you or to display your screen name(s) to get people to chat with you. I understand. We all get bored, but this ain't the place for that. For example "Hi! My name is Sally! I'm sooooo boooored. IM me! My screenname is______." For that you can go to add_me, aim_whores or yahoo_whores. Please use lj cut for long chats. This is an open community so join and post away.
