Anyone signed in with Discord can submit an event from the Events page: a title, 20 to 1500 characters of plain text saying what it is, when it starts and ends, and a link if it has one. It can start up to 12 months ahead and last up to 14 days.
League staff read every event before it shows. Community events about WARDOGS get approved. Adverts, hate and anything off-topic do not, and you get the reason in the bell.
You can have 3 events waiting at a time and submit 5 in 24 hours. You can change or withdraw your event from the submit page. Changing an approved event takes it off the calendar until staff approve it again.
