Call of Duty Modern Warfare - Help

Hello im wondering how u join / create a clan , Ive only noticed that u can put a clan tag and nothing more!

Help please.

I think you just get other people to get the same tag as you.rockguy92

thats all it is to it nothing special

Thanks alot guys..

tough they should give us a place to check which people are using the same tag instead of just suprisingly see them when the game is about to begin ;)
