Hi Gary and welcome
First thing to do is go to FSAirlines and register (it's free). When that's done, you can apply to join us. DM will send you a joining letter instructing that you register here (that bit you've already done) and on completion, your application will be accepted

Next.. let us know what aircraft you'd like your first training rating on and that will be issued. On completion of 6 training flights, your status will change from Pilot Under Training to Pilot and a full rating on that type will be issued. Then.. you start making virtual dollars for yourself and the airline
The aircraft you choose is completely down to you. You'll be under no pressure to fly all the time (no rosters) or on a particular type. Our routes are taken from RW period timetables so where a particular company flew with a particular type.. you will see routes and aircraft to match. We ask that 10 fare paying flights are done on a type before requesting another. You don't have to take another rating so if you're struck by one type, you're free to fly that for as long as you wish and as often as you wish. There is a 3month cutoff period with FSA.. something we have absolutely no control over but all you have to do to remain current is to login at FSA once every 3months.. there is no requirement to fly
On the subject of type ratings.. should you wish to apply for another at any point after you've completed 10 fare paying flights on your current type.. your next TR will be 4 flights before a full rating is issued (as opposed to 6). If you don't fly a type for a period in excess of 12months, your rating will be considered lapsed and you'll be required to do 2 refresher training flights upon completion of which, a full rating will be re-issued.
For details on the various penalties and the way FSA works in more detail, see the training forum
Now.. additional freeware aircraft with 'flyable' VC's.. that's a difficult question to answer.. especially for me who (to all intents) retired from VA flying some 3 years ago. It'd probably be easier for you to fire a question off in the crew room asking if (for example) anyone knew of a decent freeware 'Aircraft A'. One of the current pilots (or forum members) will get back to you if they know of one
Anything else we can help you with, don't be afraid to ask
