No approve button for new user

what I would love to be able to do is write my own function on the WordPress side that implements some logic (in my case, as simple as checking for a tag on the user) and rejects the logon if that criteria is not met.

@markwill

do you know if there is any hook I can user that would allow me to implement that logic?

Yes, this topic describes how to do what you are looking to do: How to prevent some WP users from being able to login to Discourse. The second post in the topic has two example functions that you can use. You will need to supply the code to replace the /* Some condition that returns true if the user doesn't meet the membership requirement */ comment that is in the code example.
