Status bots
A bot of your own that shows your server in its Discord status.
E.g. “WDN 1 · 12/100 · Ozeti” right in the member list. Create a bot in the Discord Developer Portal and add its token under Settings → Status bots (ST-34).
Profile text: the bot can also show a bio when someone clicks it, e.g. your website, the join code and a link to a channel. Write it under Profile text; the join code is filled in and kept up to date by itself.
