I’ve enabled Google Talk for the UUHEC.NET domain, I suggest I set up accounts for all of us, it’s a nice little service, based on Jabber, so you can use any client you wish (i.e. it’s not limited to Google Talk). Personally I’m using Adium, being a Mac user.
Please drop me a note if you want an account, I’ll then set this up for you.
If you already have a Jabber/Google Talk account, I can be reached at admin (at) uuhec.net
