You should be able to go to the referrals link and copy the info for the one that you want (the letter and numbers and stuff that are near the one you want I dont know what they are called lol) then go to your signature under usercp and paste it into the signature box. That should be all you need to do unless you have too much in your signature then you will need to get rid of a line or combine lines. I think you can only have 6 lines in a signature. Try that if not....wait for Sunshine Guy to come back because Im clueless after that.
