As you probably know, we use Track Groups here on ManiaExchange to manage Knockout tracks. We're slowly expanding that system to take in other groups of tracks you may want to easily find, and hopefully it'll eventually be easier to find the groups themselves, perhaps with links back to the group from each map page.

For now the main benefit is that the track has a little line of text in the track details showing that the track is in that group. Also you can open a group below to find all the tracks that have been added to the group so far.

My question is, what competitions or events are we missing? And are we missing any tracks in existing groups?
