FYI,
Admins,Global Moderators and Moderators.
Even though there are permission settings for them.
Some settings are hard coded.
For example a admin can edit delete any post from any time period. Even though there is a setting.
They just get ignored even if you set the time or can edit to null.
There was a directive for future versions to adhere to all the permissions for all groups to stop the confusion.
But we are still waiting.
