A lot of good insight here and I apologize if I started a problematic topic (with Ambassador Boards).
I wouldn't think it should cause segregation or cause anyone to think others believe they are better (or at least it shouldn't), more so just a place to go to have a conversation with all the ambassadors... maybe about the latest gear we all just received. I wouldn't expect ambassadors to stop commenting on the threads here, but would kind of be nice to discuss issues that only deal with ambassadors with other ambassadors (when the site is larger) instead of having to message each ambassador (who knows how many that is) and not be able to have fluent conversations with each other.
I don't think it would stunt the growth of the community since everyone is already fighting to get to ambassador status, so it gives them even more to look forward to, another challenge and reward along the road to ambassadorship.
I mean, if I came here today and saw there was a board just for ambassadors and a board where everyone is commenting and having a good time, I wouldn't be turned off by it, I would be more curious to see what it looks like and what goes on "behing the doors".
Maybe it's just my curious nature that would make me just as into the community or work harder but I would think the last problem would be reduction in members.
