There is no longer a need to install ICQ if you have stubborn friends who refuse to convert. AOL Instant Messenger now allows you to add ICQ numbers to your contact list, and allows you to chat with them as if they were running AIM. Apparently you can even send them files and open a direct connection.

Give it a shot!

I still haven’t been able to sign into AIM using my ICQ number, but it gives me a strange error when I try. If anybody can figure out how to do it, please let me know.
