Why certainly! Please take off your shoes before entering
Anyway, there a different forums with different categories. Whenever you have a question, pick which category you think it best belongs in and post a new thread. The PF Lounge (scroll to the very bottom) is, mostly, just for fun, especially the General Discussion. This is where you can talk about things that have no relation to science whatsoever. You could also read the guidelines to make sure you follow the forum rules: https://www.physicsforums.com/threads/physics-forums-global-guidelines.414380/
This place really enforces its rule, but that's what makes it so friendly and inviting
