Clans are for games like Black Ops. They literally have a system where you create a clan and add and take away members. Storm 3 doesn't have that. If you were planning to create a storm 3 clan, I would suggest a change of gamertag, such as "NS3 Chicken". Then, whatever someone's gamertag would be, it would have NS3 in front. Like, "NS3 Pikachu" "NS3 Dogma" for example. Those are all random, obviously you don't have to make your clan NS3.
