Hi, It's not too tricky to learn OCTGN for netrunner. I haven't had any problems with people on there. So long as you either mark your game with Learning OCTGN, New Player, or something similar then people are usually happy to help you get started. Alternatively, if you join a game and tell the game's creator that you are new, that should work fine too.
I'm at work at the moment or I'd suggest we played a couple of games.
Good luck, have fun!
