The board now has a "Statistics" section towards the bottom of the main forum listing. We've also added some "transparent" modifications for admins and mods.
As always, if you would like a feature added please just feel free to ask.
How about making the number that shows how many posts were made in a thread into a link to a popup window that shows who posted in that thread, and how many times they posted? This feature is in use on other forums.
