They should divide the plastering section into 2. 1 for newbie questions that may come across as silly, and one for time served plasterers. that way if you don't like reading obvious questions don't go on newbie section
If you never went in the newbie section who would answer the question and i think a room just for time served plasterers is stupid idea, what would i do in there on my own?
