What's being done to make sure users are aware of these magical requirements?
And I don't mean retro-actively (notifying current leaders), I mean new users.
I suppose that's reasonable, but how will the discourse software platform communicate this to it's users?
Because your proposal of coupling trust level with "likes" is kind of invisible to most users, it's "magical" in that sense and not a convention that I think I've seen anywhere else.
How does my mom know that "liking a post" has more significance than just communicating that she likes something?
