If you don't know and don't ask, you will never know, no such thing as a stupid question, only stupid people who ridicule the question,
generally with less knowledge than the person they are slagging off, as previous poster says, asking questions not only helps you, it may well help hundreds of others too scared to ask.
The only real stupid question is the one you were too scared to ask through fear of ridicule, because you and others learned nothing. Anyone ridiculing a question, you might want to ask yourself are they really the type of person you want answering it.
