Want the Xfire stats but not the lame standard signature? Check out Custom Xfire Sigs (CSX).

. . . you can customize your signature. Move the info around, use transparent backgrounds and/or avatars, translate it to your own language or change things around.

I tried out this free service and it is pretty cool for those that want Xfire stats in a fancy sig. Make sure to use the advanced options to tweak the placement and color of your xfire data.
