This thing rocks, just installed the rpm and away I went - instant messaging folks in aim, msn, etc. and it was great. A couple of the reasons I wanted a console type IM was:
I'm in Linux often, so its easy for me to just pull up a second ssh session and use it solely for CenterICQ.
The second reason is because I did not want to deal with all the software upgrades and BS that those parties (AIM, MSN, etc.) want you to install on your machine (be it malware, etc.). Not to mention the things that get changed and manipulated on your OS (in my specific case it was with Windows).
I highly recommend this application to anyone who shares in the ideas I provided above.
