We did this quite a while back but it’s been so long and we have such a lot of new people here I figgered it was about time to do it again? If you feel like letting other Doers know what your Instant Meesenger handles are, post them here! Also I think it might be interesting to list whether you do any webcamming as well.
Mine :
AIM Euty55
Yahoo Pressmanslim (w/webcam)
MSN (none)
ICQ 32080783
Oh, I’m a Doer. Sometimes I’m a Want-to-Doer, though. Sometimes I’m more of a Procrastinator. I’m also occasionally a Forgot-to-Doer.
AIM SirHappy70
Incidentally, a good rule of thumb for this thread might be that if you’re going to IM someone from here whom you’ve never IMd before, please say you’re from the SDMB in your first message. Some of us have a tendency to delete unfamiliar IMs…
By the way, here’s an old thread we did on this, although it was just for AIM/AOL people.
