Do you feel the forum is difficult to use? Is there anything you'd like to know how to do?
IMO, too many categories (for thread topics) with too few number of new posts makes navigating more difficult.
EX: Five different classified sections > one would do.
IMO, when there is a lot of activity (several pages per day for example) then it makes sense to sort out the interest.
When on a post or two per day then combine it with similar interest.
This would make daily reading much easier, IMO.
Quality not quantity from my point of view.
