Thanks for the speedy and in depth response, much appreciated. It seems, however, that users are only created upon visiting the forum when that option is selected. I can utilise the API to create users as mentioned but was curious as to whether I was missing something as the setting reads as though users should be created straight away.
This is for a client and they are using memberpress. Everything regarding user levels is already hooked up and working it’s just the initial creation of users that was confusing
