You can just ask in the
Community Chat, for that. A questions forum would be very silly, because threads would be closed wicked fast. If you have to ask where the search function is, then as 5D911 said, chances are you aren't going to use the right forum to ask the question either. I know you were just giving an example, but a forum like that would practically be designed for people who can't just read the rules.
Forum Guidelines are in the top left. Search is in top right. What else do you need to know?
