Chat with me...
I added a widget on that allows you to send me instant messages from fingertoe.com.
Meebo is pretty slick. It is an website that logs in to all of your instant messenger accounts and allows you to interface with them all from a single interface.
Since it is hosted on a website, there is no software that needs to be installed, and you don't have to worry about any of the typical security and firewall issues with other instant messenger clients.
I am able to log into ICQ, MSN, Yahoo, and gtalk/jabber all in one place. The downsides are having to devote a browser window to meebo, and not being able to do file transfers.
