how does a clan work

just like the title says, i am wondering how clans and those type of things work? i have seen some on forums and i am wondering how they work, what they do and all that. all reponses are apprecaited.

 

Well when your in a clan, you usually practice with your teamates and practicing certain things. Then you usually duel other clans. Thats basicly about it.

 

I am assuming you were referring to 'Gaming Clans'?
Addition to what the other person stated, it is pretty much a community for gamers with similar likes and ideals. As with any community they have certain rules and goals, etc. If you weren't referring to gaming clans then disregard and be more descriptive if oyu can.
