Hi John
Thanks a lot for your answer.
What I’m talking about is a set of groups that exists across all sites in the multisite, and where a user is either part of a group on all sites, or not part of the group on any site.
But I was kind of contemplating a different approach, so my follow up question would be, whether it is possible to programmatically assign a user to a group – perhaps based upon data in user meta.
In our use case it would probably be something like, if User A has seven digits in a specific user meta field, then he/she is assigned to Group 1, and if he/she has five characters in another specific user meta field then he/she is assigned to Group 2.
In order to work this function would somehow have to run on each site, every time a user/administrator creates or updates a user profile. Or alternatively I guess it could be triggered as a cron job on each site.
The benefit of this approach in our user case would be, that the site administrator would only have to worry about updating the relevant user meta fields, and not about manually assigning users to groups.
And yes, if we where to build this functionality, we would definitely need professional help.
Best regards
