that would be cool. How big can the clans be?
Maybe we can have Fizzer (creator) create the option to add a clan tag to a name, that way, we don't have to change our actual name at all and if we do, we don't have to change the clan. I think someone should write a uservoice item about clans because i don't see one created.
here is one that could work as well:
This UserVoice item would create Leagues of people and I think that would serve as clans.
