Well I know how much work it would take if it was possible. But what I would change is to make an option that lets you create a clan and a tag automatically shows on your name. If you ever played any of the "Socom" games on ps2, you know what
I'm trying to explain. But that would be alot better than just adding a tag to your name. Plus it would help by eliminating the people who just add tags to their names and try to "act" like they are in the clan.
