It's not permanent -- but it's live. That's the trade-off.
I hardly ever participate in Chat rooms or the rest of the activities in this category, so I haven't developed this page yet. I am trying to get one of my friends who does participate to log off long enough to write something for me. If you want to volunteer (or to volunteer someone else who susceptible to blandishments like a lifetime supply of Virtual Chocolate) please email me.
I have collected the following info about ICQ:
The program is currently (and has been for since its initial release) free and listed as a beta. They have no plans on changing this at the moment. It is an awesome util for anyone who uses the internet. God knows there are a bunch of people now trying to play catch-up to ICQ with their own pagers....none are as capable or as widely used.
Chat rooms are live "conversation" between any number of people.
