/r/NewToTF2 doesn't have any sort of limit on how new you are! It's more of a friendly no-stupid-questions kind of place. Also yeah, 200 hours is still pretty newbie compared to some of us! I just got to 1400 hours and I still have a TON to learn.
But yeah, don't feel uncomfortable about taking advantage of /r/NewToTF2, we'd love to see you over there!
