This add-on allows you to create custom leaderboards in the Admin Control Panel (Users -> Leaderboards) which appear as tabs on the Notable Members page.
Leaderboards can be set up to use any column in the xf_user table, including any columns added by third-party add-ons. This includes message counts, number of trophies, likes counts and more.
Leaderboards can be set up to only include specific users based on the usual range of criteria, such as limiting to moderators/administrators only, users who have made a certain number of posts or received a certain number of likes, etc.
Due to the extra processing required to produce the leaderboards, the leaderboards are produced in the background on a regular schedule (hourly, daily or monthly). This can be set on a per-leaderboard basis. Optionally, the date that the leaderboard was last rebuilt can be displayed.
