My user name is firstname.lastname@example.org, which also is my email address. My email was automatically selected because I have an existing Yahoo account with my email address as my sign in.
I'd change my user name if I were to keep this as a permanent account.
The Yahoo! web-based IM service appears to only accept messages if I am signed into the account with the page open. That makes sense. IM wouldn't be very instant if the messages were accepted and stored for later reading. I think that would be called email.
I've used more than one university library's IM service to chat with reference librarians. The experience always has been good. Fast retrieval. Smart answers.
Confession: Once a caller to my workplace at a magazine wanted to find a story in an old newspaper that is no longer published. I admit that I established two simultaneous IM connections with reference desks at two universities to help out the caller. One library was particularly fast in telling me about a third library where the newspaper in question is kept in microform and I was able to help out the caller while he was still on the line.
