Clan tag in front of name

[bornoffire]

I was looking for something for my members where they could go into there usercp and put in there clan tag (example: POW) and from then on my name would be [POW]bornoffire . Any way this could be made? It would also be cool if this tied into the social groups. So a clan could make a group and everyone in that group would have the clan tag for that clan in front of there name.
