Discourse (the software powering this community) offers tutorials in the form of a conversation between you and a bot named @discobot. There are two tutorials, one for new users & one for advanced users. To try them, create a message (click your profile picture, then the envelope icon, then New Message) & send a message to @discobot. Put whatever you want to in the subject & make the message either:
When you complete the tutorials you get a “certified” badge (new user tutorial) & “licensed” badge (advanced user tutorial) & a certificate suitable for framing!
