Stephen, it sounds like your firewall was blockin' ya

because Yahoo IM! should be working fine --
I'm on various IMs but I don't sign in most of the time because I am trying to concentrate on something and don't want to be interrupted. I have a hard time staying focussed. I have to be serious about eliminating distractions

or I'd never get
anything done!!!!
A chat room might make more sense since it'd always be online whereas people come and go.
If Michel uses a cPanel host, there are 2 chat rooms which should be easily installed and could be run on his account 24/7.
I've also installed
GTChat on several clients' accounts (it's a manual install) and have been really, really happy with it. It's easy to install and
very light on the server. I think it'd meet our needs perfectly. Link:
GT-chat - Home
HTH!
