I noticed the hierarchy in the Forum, so I mean to ask, are there some sections I need to avoid since am just a newbie? Can I contribute to any thread despite the OP's rank?
Once you see the add new topic or reply buttons, you are free to post in that forum section. But most importantly, you'll find plenty of guidance in the
Beginners & Help board. If you read over the regulations there and comprehend them better, you won't encounter any issues with your forum activities.
