Well I just start to play on forum, and I made my first thread here, this is my second and I saw Killercyber has a clan : Fake Tori, how to have a clan and how to join a clan?
If you just started playing this game, I recommend joining Bleu, which is a clan for beginners. However, if you know of a clan that you have some friends in, you can try joining that clan. You can apply for any clan really, just pick one from here. You probably won't be able to get into the majority of the clans you see, mainly because you're just starting out.
