How can I display my XBox Live Gamercard or PSN gamercard in my profile.

Your XBox Live Gamercard or PSN Gamercard will be displayed in your profile if you have entered your Gamertag or PSN ID in the appropriate fields in your user profile. Please note that if you have both a XBox Live Gamertag and a PSN ID only your XBox Live Gamercard will be displayed.
