As a teacher/instructor for many years I know the only dumb questions
are the ones you don't ask. If you ask, you risk getting dumb
answers or insults from those who think they know it all, but usually
don't. I have left other forums because of the macho know it all
attitudes. You might find 1% of that on this forum, but generally most
are understanding and helpful. Keep asking. Ignore the 1%
