I usually zap the winners bc of previous experience where the sponsor wasn’t online at the end of the contest, you can send it now or when I message you 3 days before the start of the contest, you have 200 characters you can fill with whatever text + npubs + links you’d like and as of recently I’ve been playing with the idea of letting the sponsor have a say in what the theme of the contest is (as long as it has something to do with nostr or bitcoin) so you can pick out that theme as well if not it’ll default to nostr themed meme contest
