Hello, I was wondering if the must_approve_users site setting still affects existing forum accounts or if it only sets new registrations from that point on to approval. We are using Discourse version 3.3.0.beta2-dev and the site setting option for that no longer has the revocation warning in the description (attached is what we see) so I thought I’d check first and thank you. 
Hey @deeann 
Welcome to Meta!
All existing users are be marked as approved when you turn on that setting.

Though sometimes this does not work
@Moin hello and thank you! That is great news and helps a lot in the decision to change it.
