There arn't any stupid questions. Just stupid answers from stupid people.
So don't be afraid to ask, but try the search first, if no luck just ask in the proper place.
You can't see anyone laughing anyway.
I been asking stupid questions for 55 years and I still do.
You've got the 'Welcomes and Introductions' forum for basic questions and intros, so feel free to ask there. I don't think there are any stupid questions- other than those that have already been asked- and there are plenty of categories on the site where you can post them.
