There seem to be varying definitions of moderators. As far as I know:
- In Discourse, trust level 4 is what most people call moderators. They moderate the discussion in the forum.
- What Discourse calls moderators are people, who have nearly administator rights. They are staff of the forum. They have rights to flags, they can ban, they can suspend, they can almost everything, except change the basic structure of the forum (which is up to admin). In short, Discourse’s moderators are moderators of the site, not the discussion.
