What I would like to do is charge members for a certain trust tier. So basic (free) users can do most things, but ones who pay get special privileges. Is there a plugin or something that I can use for this?
You would click on the search function at the top right of your screen and enter “crypto paywall”. This would give you this as the first answer: Discourse Unlock

The Builders group would for example be the group that people pay subscription access for.
You are free to add the everyone group as well and remove the create and reply permissions. So everyone can see the posts (no paywall) but people have to pay to create topics and reply to them.
