I had to hunt down my ICQ number the other day, which I seem to do occasionally over the years.  I use it for a few weeks, then delete it as useless.  I used to use it a lot, but email is much more useful, generally.  I even have an early number:  529564.  It is becoming more difficult to find it, so here it is.  Preserved until this fad wears thin too.  Of course, the client really stinks, since AOL bought them out, but the new Trillian client is pretty nice.  And it integrates Yahoo and MSN IMs too, which I have by default of possessing accounts there.   Let's see how long I use it this time...
