Heh, dont worry bout sounding stupid, im sure I sound like that half the time.
As for how to post them read the thread just above this one, good ol Rifleman has it all right there.
As for taking the screeshot from your sim to begin with, just hit the "Prt Scr" when you want to take one, then pause the game or have it paused when you take the shot, then use Alt+Tab to switch out to desktop then startup "paint" or some other similar program and when it opens, use Ctr+V to copy the shot to the paint program & save it however you like.
Then you can just minimize paint and go back to FS by maximizing it, and fly some more.
