Some Ideas on how to learn the game better:
1. It has already been mentioned, but learn everything there is to know about the radio and communication. This includes ".dot" commands like .move, .salvo, .wingman and so forth.
2. Find or follow someone that knows what they are doing. When I was really new, I would get shot down before I knew I was in trouble. (Now I still get shot down all the time, but I know I'm in trouble
) So find someone who knows what they are doing, and watch what they do. Training arena is a good substitute here.
3. Find a squad that is to your liking. You will learn all kinds of stuff from the veterans in the squad, and you can have some friendlies that will help you survive a little longer when you get yourself into trouble. It is always better to fly with at least one other person than flying alone.
4. Watch the Mission editor, and join a lot of missions. You will get to see how people plan and execute attacks. It is also a great place to find a squad you would like to fly with. Not all squads are active in making missions however.
5. Keep reading the message boards, and find the links to the good reference sites like netaces.org.
