Discourse has two settings that may be helpful for your use case:

- **mute all categories by default** , so all categories are muted by default and users should opt-in to the categories they would like to see on their topic lists
- **default categories normal** , to set what categories you want to be opted-in by default, so new users don’t end up with an empty home
