I have to say, I think it would be a mistake to take away the NA forum. It really has nothing to do with the language we speak, but the common timezones we share. I agree it is invaluable to get out on the main forums and mingle with the rest of the world (literally) in our community - admittedly something I am guilty of not doing as much as I should. There is seemingly infinite knowledge here about sim racing and beyond, and it would be a pity to not utilize it to its fullest capacity.
The purpose for the NA community is to create our own little niche in the club - easily schedule races the majority of us can all participate in and form a close-knit community in the process. It is by far the easiest access point for new NA prospects, something we have notoriously been lacking. I can say from personal experience, without a NA community this experience is daunting. When I joined up there really were no NA races, much less a community. Luckily Yves and a couple other guys were just starting to get the ball rolling and I happened to stumble across the proper posts (along with some well timed PMs by some of the NA admins). Ever since the inception of the NA forums we have had a huge spike in interest - it has served as a home base for all new members to ease into the community.
Again, I believe that this forum should be viewed less as a segregation and more of a regional organization tool. I won't have any hard feelings if you guys decide to go in another direction, but I do think we should think about the effect it would have on growing the regional community.
One more side note: I do not believe that this is hindering international turnout for our race events either - in fact I see it helping them. We seem to be getting a lot of international regulars joining the US events, especially after they visit the NA community and have more interaction with our members. Rather than just being another timezone to race in, international folks are enjoying our race events and are seeking them out due to the community atmosphere.
All things aside, I want to thank Eric/Yves/Tim/Marcel and everyone else who has pushed hard to develop what used to be a very small group into a thriving success. Well done on all accounts guys!
