New to the idea of a clan...

Hey guys! So, I've never played with a clan before... in any game... ever. Is there anything special I need to do to join? I'm a pretty casual player, and have taken to mostly solo playing (I like to sit back and rack up the headshots, but am also equipped to jump into the middle off the fray). I wouldn't mind having people to game with too. I love anything pve related, and I'm up for raids, but sadly am not very experienced with them. Also I'm awful at pvp, sorry. Still willing to play though. Level 31 Warlock, vw and ss maxed. (I have a few exotic armor pieces I have on the side lower me to 30 but I'm working on that). I'm working on a nice collection of exotic guns, but mostly have gotten super lucky from the occasional nightfall drops. I play on the ps3, my gt is lyricalrequiem I have a mic, but don't always use it (I'm sure I'll use it more with friends to talk to!)
