my suggestion from one new guy to another, go in, pick a side. talk on f12 to those around you and work with them. if you're not comfortable talking to them just listen and learn.
there are great people on both sides that will help you along. i've probably shot my mouth off once to often and maybe pissed a few off, but theres always someone willing to help you out.
if you see a bunch of planes forming up on a runway, ask where their headed and see if you can fly with them. they'll always take an extra player if one is available. you can use f12 to talk or type on the country channel and let them know you're new and would like to participate.
its truly a fun place with lots of things to do!!!
if you join axis look up tbarone or storch or stampf or even truekill. they are the most knowledgeable people I know. thats not to say there arent others out there, but these guys are the ones that took me in.
above all have a good time!!! i hope this helps
