Let me straight things up here.
Clans are just group of players who play under the same tag. Some clans are more competitive, others focus more on having fun (not that competition can't be fun). Just look through the ac clan list and try to find a clan that fulfills your desires.
My advice is: play AC, hang out on the IRC and get to know ppl from different clans.
Edit: Some clans require you to be at a certain skill level, others don't. Take that in account.
