Additional Group permission for ID/Age Verified with seperation of the "18+" and "Age verified"
My example is "@Everyone"
These are normally new users to the group with zero permisisons
I suggest that another role for users that have the "18+" or Age verified tags on their account.
This allows new users to the group or anywhere in the future who are 18+ or Age verified to jump straght in to group activitys without needing to undergo some process.
