TMUF-X
TrackMania United Forever is not being tracked yet
The remaining list needs an archive of who finished which map first. That archive exists for TMNF-X today; the other exchanges are next.
What is missing
The map catalogue is easy — a few hundred requests to the exchange. The hard part is attribution: working out who was first on each map that was already finished before this project started watching would take one request per map, and for a site the size of TMUF-X that is hundreds of thousands of them. So the archive gets imported from the community spreadsheet instead of being rebuilt from scratch.
In the meantime
Everything on this site already works for the exchanges that have data.
