For the dumb question responses, please don't be like that, if we all start asking ourselves is my question going to be classed as dumb we will all loose out!
I have a question that I was already pondering asking in case it was dumb, now I may not ask for fear of ridicule, I probably will ask it because of the philosophy I have when I am dealing with my specialist field.
There is no such thing as a dumb question, just one you don't know the answer to.
