Add block permissions?
The following area permissions are inherited from the page's permissions.
Add Block to Area: Administrators
Add Stack to Area: Administrators
How do I edit the page permissions to avoid over-riding all the areas?
You cant change block permissions on the page. for the block permissions you have to go on yoursite.com/index.php/dashboard/blocks/permissions/
click on add Block and then on details there you can specify withc kind of block every group can add..
