CTFtime can be offline from 10.06 22:00 UTC - 11.06 06:00 UTC for reasons beyond our control. Beware if you use OAuth as login method for your event. Sorry for inconvenience.
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.
If you wanted to join empty team for long time and request was in "pending" status - check it at your profile page now. ctftime.org/profile All the pending requests created pre 2020 will be autorejected soon.
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.
