This is a really easy one but it took me a bit to figure out actually and the answer turned out to be really easy.

I wanted to be able to sign onto xfire from my laptop which is MINT at this time (by the way my favorite distro ever)

Anyways it is simple as adding the gfire package which is the pidgin plugin for xfire

sudo apt-get install gfire

This adds the option in the dropdown list for the xfire protocol

Its as easy as that
