How many admins are there?

 More admins

Yes, there are different types of admins: Jira admins, project admins, board admins, organisation admin, site admins, user access admins, system admins (for Jira yes)... This really gets confusing, especially if you would need to memorize everything. Why there is an org admin and site admin and that's it. Nothing more, nothing else. Let us break down these admins, shall we?

• Product admins - They administer the inside product depending on the group membership AND they necessarily need product access - huh? Product admins without the product access...
• User access admins - They administer users and groups and they don't need the access to the product....but how you will do this without the access to the product? I don't use this at all
• Site admins - now we are talking, they manage new products and apps plus with the users for ONE specific site
• Org admins - they have the highest admin privileges and they manage everything. Usually the ones who create the organization are also the organization admins

 There are even billing admins. Don't believe me, check this out: Different types of admins 

 Of course you can make someone a product admin, and these are the user access admins.
