Okay, but I can’t have a long list with every user on that page.
Can it work with any group plugin?
I have testet:
https://da.wordpress.org/plugins/groups/
https://da.wordpress.org/plugins/user-groups/
https://da.wordpress.org/plugins/wp-user-groups/
And when i add the Admin i get:
Invalid username
Is there anyway i can implement a group plugin, that can act as a username?
