I think a list of ranks and such (see Kary's post) would be good, and I also think that if you have the guild favoring DWARFS only, then you need to have a lot of support and groundwork for it. Set up a website, contact several players Ingame, and talk to the locals about what they would think. Also, your guild (again see Kary's post) needs to have a point or purpose, it can't really be just a guild to "hang out" with people, that won't last long. Good idea, just needs some groundwork laid out for a strong foundation.
