Rounds are running from Tuesday-Monday, payments are going to be made in the next 24 hours after a round has ended.
New enrollments are only going to be made into the next upcoming round, and are announced right with the payments.
There's been a small update to the campaign rules, rounds are running from 0:00 forum time on Tuesday to 24:00 forum time on Monday (that's UTC).
Payments and announcements will be made in the next 24 hours after a round has ended, meaning payments will be rolling out every Tuesday.
