Linux

IRC

If you want to contact me via irc my main handle is aimee_maree and I can be found on freenode server, 
most times on #debian or #fedora

http://freenode.net/

Two irc clients I recommend;

Pidgin > More User friendly nice GUI  (both for Linux and PC)  http://www.pidgin.im/ for security you will need to add encryption http://pidgin-encrypt.sourceforge.net/

ISSI > Command Line based highly secure not as User friendly as Pidgin but ultra fast and secure  (both for Linux and PC)     http://www.irssi.org/
