Since October 2020 it is possible to upload replays to TrackmaniaExchange. With that the well-known leaderboard function also returned. Based on the replays that users upload, they rank differently in leaderboards. The October update also saw two new functions being added to the website. 1) There is now a seasonal leaderboard, and 2) every user can create mappack leaderboards.
Mappack Leaderboards are a super useful function: You determine which maps should be part of a mappack and the mappack leaderboard then shows the best ranking players on just those maps. Ideal for organizing competitions or creating targeted leaderboards.
This subforum lets you share your leaderboard competitions and custom leaderboards!
Please make sure that you 1) do not create leaderboards that already exist and 2) try to give your leaderboards a theme. Leaderboards for competitions make a lot of sense, for example.
There are also some official leaderboards that you can see as stickied threads in the subforum.
