I've been using IRC for ten years. Started on java at talkcity.com, then just some off and on stuff with some harry potter fangirls until magic hogwarts started up, then I started using the chat there, found out how to really use irc (not on an applet xD) and have lived on it ever since.

I still use the same ISP e-mail handle, but since our isps have changed, the part after the @ isn't the same any more xD
