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.
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.
Some CTFs had to shift their events time this year b/c of all this COVID situation. To keep event weights consistent with previous years we decided to increase time window b/w events used for weight calculation to 18 months.
