You can now enter and display your XFire account in your profile. This is due to the recently added PC rule of required to have XFire. The reason for this is we can keep in contact in pretty much any game and have a list of games we play just by playing the game with XFire on. Also you must be in the clan on XFire which will be used to display the PC members in the clan. Please check out the new rules for further details.
