Could you elaborate on the sort of theme you are intending to go with, being that it is using your material rather than a published setting? Something more sword and sorcery, traditional or comparative high fantasy? A hopeful world or one tainted quite dark? Things of that nature, as well as those associated with what levels and materials you are making available, such as if other books and Unearthed Arcana are valid pursuits. I suppose the point is, what more can you tell us?
I would also like to inquire about the rate of posting and effort you are looking for as well. The Guild has a strikingly bad habit of people failing to post and more or less killing the interest of everyone else involved, thus dissolving the topic in weeks if not months. So for myself, I would rather not throw my lot and effort in if that is going to be an acceptable norm.
Do let me know your decision,
