I fear there aren't many that hang around here anymore. It's really a shame as most questions about a flute seem to lead to old posts from this site. Your new acquisition sounds like a pretty nice flute if you got it for a good price but I'm finding that a lot of folks that play flute for a living seem to dislike Gemeinhardts as well as Armstrongs (like I just purchased). The mechanisms might need a little more attention than the preferred brands but I think they are a helluva good bargain once they hit the used market! I'm sure that there are much better choices at retail prices for new instruments but I get a better sound out of my Armstrong than I ever heard out of most of the lower tier models of Yamaha. Your Gem is no doubt in the same category.
I hope you will continue to check in here. Maybe if we at least have some bodies here to respond to posts there might eventually be enough flutists to answer questions that people go through the trouble to ask here.
