One thing my users are asking for are top ten type of lists. They want to know who has the most posts or the most likes and whatnot. So I am suggesting that in a future version of wpForo is a Top Ten Widget.
A widget that you can show the top ten users of a particular stat. Posts, Likes, Dislikes, Points, Topics and the like.
Just a suggestion...
This might be available in the new addon called wpForo Widgets.
