Not a huge thing, but it always bothers me that the latest topics listed on the main page are filled with old sticky topics that never go away, effectively hiding the 3 latest topics in a category.
Perhaps the sticky topic links could be the in paragraph of text below the category title. Like, where it says “Select a General…”, just put New User Guide and Check Your Profile as suggested topics before posting.
I would apply this logic to all the major categories on the main page and maybe increase the number of topics listed from 3 to 5, if it doesn’t look too weird.
Anyway, food for thought.
