Ok, I see your point, but:
1. The engine, by its nature isn't really user friendly. It's nice designed and implemented and developer friendly, though
2. The community is not quite big, maybe because people are more comfortable using c/c++ for making games, because this way has much more traditions and people have done it many, many times
3. There's a Feedback subforum already. Everyone can share what he/she has done. If the information that can be clearly classified into category 'Tutorial' grows it can be moved to another specialized subforum, but this is not the case in the present moment, I think.
