Hello! It's nice to see another brassist here. I'm a bone player myself, but I don't do too much playing outside of paid gigs and uni. I should change that when I can be bothered to get a decent recording setup.
This place gets a bit catty at times (or fairly frequently), as the size of this community guarantees that certain people won't get along. However, it's fun. Most notable people here make a point of being friendly and approachable, as that's the entire point of how this game can thrive. You'll enjoy it. Don't try too hard to fit in and be relaxed and you'll be totally fine.
