I think that on the "Profile" tab, under the first section, in the Contact Info area (Email, Skype, MSN, etc.) you should add a section for the gamer's PSN (PlayStation Name), XBL gamertag (Xbox Live), their Wii name, RSN (RuneScape username), and their WoW username.

I'd be helpful, and easier to find people online besides this fourm.

Excelent suggestion, I have added it myself. You may edit this in your profile
Cheers!
