Something I’d love to see could look like this:
And then, as @c12gene mentioned, have all the relevant settings in one place.
I had done a how-to on modifying the onboarding process before (Welcome new users with customized trust level promotion messages ) What I see makes this difficult is that there are multiple parts that play together, but they are spread out through the admin backend (system messages, discobot, default texts).
Another aspect that I find is complicating adjustments is actually the “discobot” as such. By now it feels a bit like an outdated gimmick overall and it even might cause confusion when having other/multiple ai bots on an instance. I could see it more helpful if this bot would just be presented as a plain user-tutorial feature.
