You know what else is a great sign? (At least in the Rook side) People are willing to help when called. When people do act like dicks to them, we scold them and sometimes they apologize.
Personally, I helped a guy from England who have been playing War Thunder for years. I explained the importance of strats, porking, functions on the clipboard to help with intelligence, etc. He was ecstatic of the gameplay. He told me that he was going to get his roommate signed up.
