What we show

Name, organizer, listed prize, deadline, format and a link to the official page. Summaries are written from those facts, not copied from the event page. When a source does not say whether solo entries are allowed, we say so instead of guessing.

Featured events are always marked as Featured. Paying does not change any other detail on the page.
