Pidgin

I like pidgin for chatting when ever I'm running Linux.

add debuntu repo and gpg key:

slash@shaolinint# echo 'deb http://repository.debuntu.org/ feisty multiverse' >> /etc/sources.list
slash@shaolinint# wget http://repository.debuntu.org/GPG-Key-chantra.txt -O- | apt-key add -

update repo and install pidgin:

slash@shaolinint# apt-get update
slash@shaolinint# apt-get install pidgin

And that's it, simply 1 2 3 :)
