We fixed a bug with team name parsing (sanitizer was too strict) and updated some scoreboards - there can be slightly changes in 2021 team ratings.

Wanted your team alias to be displayed at scoreboards instead of team name? Now you can (not before cache expires though).

Now organizers can edit events after approval. Still require moderation after editorial. Also, you can mark an event as "casual" and it will not get any rating weight.

Important changes in 2021 event weight voting: now only teams who participated at least in 2 events can vote. Votes accepted from members who joined those teams before the event.
