Do you remember mIRC? (mIRC : an Internet Relay Chat (IRC) client for Microsoft Windows, created in 1995 and developed by Khaled Mardam-Bey, is a fully functional chat utility).
I do! I started to use it in 1999 and I can say that mIRC helped me to learn all the stuff I know about a PC (and to type really fast!).
I stopped using it after almost 3 years (I lost many hours in the Internet Cafe : ) ).
Now we have Facebook and Tweeter. But mIRC was very funny at that time. Are you still using mIRC? I'm just curious!
