Hub World ehh? Yes a bunch of us have thought of it but I don't know if it is going to happen. It would require a bit of changing around as well as a bit of work and sense of sharing from each server. Maybe each server could hire one or two developers for their section as a sort of "representative" or so?
Problem is, I don't think anyone wants to fork out $59 to do such a small project (in comparison to other server projects) and I don't know if Stefan or Unixmad are willing to give someone a free server to make this "Hub World".
