i used to use mIRC in 1996, then someone made me download this new thing called ICQ in 1997... i used it for years and i knew my number better than my phone number started using MSN a couple years later, but i've never really used the actual msn client cause i haven't had windows for years so i've been using gaim (now called pidgin) for the past like 5 years, but i dont connect to the yahoo or icq networks anymore i have MSN and skype on my mobile phone online 24/7 i'm currently looking for a multi account client (like pidgin) that i can use on my phone
First messenger I used was AIM and I still am using it. I occasionally use MSN to talk to friends who refuse to leave it
The first messenger I used was MSN Mesenger... then Yahoo, then AIM, then... I forget. I'm currently only using Windows Live Messenger, which is the best IMO.
Mine would be Yahoo messenger, was to be really fun to pass time on those Yahoo chat rooms back in college.
