Just Joining, any advice?

Hey Cowpokes,

I just started playing this and dont see too many folk around. Any advice for early folk? I was able to do one round of the Halloween zombie invasion thing in San Denis which was awesome. How do folks meet up/ppsse up and do things? And should I be doing free roam stuff?

I have a "mission" thing with yellow Scales but when I approach it makes me do a matchmaking which took forever to load and I just quit. So any advice would be great!

Also is there a way to adjust mic sensitivity in the game? Not sure if folk can hear me
