Returning Player Looking For Help ( I Remember Almost Nothing )

Hey I'm a returning player from awhile ago, I haven't played in a long time because of job and school. I don't remember much of anything and I'm looking for a chill group/player to help me relearn from scratch. I'm really laid back and mature, I'm just looking for some cool players to learn with and to have fun. :)

I have a mic but I don't know what service is most used by player for mic chat.
