I've fairly new to vanguard. Watching some of the anime and played with a friend who is a vanguard activist so to say. He's been teaching me how to play with this and helping me play around & build a few decks. I enjoy the game (can't play it irl, busy + no one to play with xD) anyways I was wondering if there was a proper etiquette guide for playing online with other players.

My friend and I have been speaking over skype so it's easy to communicate but when it's other players a few times people just leave since I didn't do/say something right? I'm not really sure on what I should be doing over chat.
