ok so i dont know if this has been found but i will let u guys and girls of ngu know because there are always new people that dont know.
so to get to the point if you want to make a clan or u want to change your clans name but cant because it is already taken well you can still have it all you need to do is follow these steps.
1.go on the COD ELITE APPLICATION on your system(i use ps3)
2.go to clan management
3. go to change clan name
4.put the new clan name you want
5.if taken then all you have to do is put a space in before the clan name like so
thats all and it has to be on the system
found by me fi3rw0rx and nicknac12(if it unless someone els found it)
if you didnt understand please quote me to explain better
