I understand what you mean by the structural arrangement. But I am talking about layout examples of what you might have envisioned, hence asking if you had any forum examples that already exist.
Reason most questions asked in all threads are actually asking for either tips and tricks to solve a problem.
Tips and tricks is a bit vague, a user or guest will look for threads that has similar questions or challenges he/she is facing , and not neccesarily
tips and tricks.
Let me provide a more zoomed out view so you can see there are indeed 3 tiers. I am reluctant to have two many things that increases the need to scroll down.
I've had a look at the Access FAQ, Code Repository etc sections and there are very few posts there. I am not sure it is worth the vertical overhead for an infrequently used section of the site. Adding multiple sublayer will increase the scrolling required to get to the other areas.
