I want nightbot to say a random user from my server/channel
such as: !slap as nightbot will say: $(user) has slapped (random user from server)
Hey @Groovy Koala!
If I understand properly you're asking for a Discord command, you can use $(provider) for that, but it won't make it easy to select a random user from your server, actually, I don't know any API that could help with that.
Nightbot isn't made to be a Discord bot, you'll have better luck with bots that are actually made for the platform.
