Terrainmonkey and hans_worst I second what Ravs and Neon have said.
Baziron and Alucard great to have you onboard. Have a look around the map, see who your neighbours are and discuss shared features with them just so everyone understand what those near them have in mind. Alucard, which is it going to be?
Terrainmaonkey, we havn't got a mastermind working on backstory, races, history cultures etc. and I dont think thats the aim here. We want the process to be a bit more organic although thematic suggestions are great to spark something in the mind of the individual mappers, as has been done in this thread by Venardhi.
Neon you got thpse areas man, although I think closer inspectin will reveal thousands of tiny atolls and island chains that require intricate mapping.
