Yes, in the spirit of open source we will share maps, textures, models etc.. I read on this forum about using QME but I found that Blender is a much better model editor and is very active on sourceforge and best of all it supports md2 file format (we imported some of the dpball and bsp models and they loaded).
Once we get proficient in making models etc.. you should see some pretty cool new concepts in maps. I have a team of young children here interested in dpball and bsp, and playing some of their maps already looks promising
