on instant messenging...

For what it's worth... my IM info is on my profile, and I don't mind people IMing me. (Note that I don't use Yahoo IM anymore so don't bother adding that.) There's also LJTalk, but that keeps disconnecting me.

However, also note that I tend to forget to set myself as being "away" or take away my away message when I'm back. So don't be afraid to send me a message even if I'm away, and don't take it personally if I don't respond even though I don't have an away message up.
