You appear to be using my invitations plugin. Could you open an issue on GitHub?
https://github.com/NodeBB-Community/nodebb-plugin-user-invitations
When a user gets approved, is an email sent to the user to confirm registration?
@ferik as long as you set up your NodeBB with an email-plugin - Yeah. There will be an email sent, and I think that you can't even post etc. before you get approved.
Thank you
