This question is in reference to Atlassian Documentation: Global Permissions Overview
In the linked documentation guide, what is the difference between the groups of "site-admins" and "system-administrators" and "administrators"? We see in a screenshot in that documentation that these groups are all listed in Confluence under Editing Global Permissions, but that these all have different permissions. What is the difference? And how do we manage these groups? I understand what "administrators" is (the application, not the site), but what are the other two? Under site administration, I can see how to manage the "site-admins" group, but not the "system-administrators". Is it a case of the "system-administrators" group not actually being a group at all, but rather that this is just the collection of users who are site administrators? It is very confusing why there are 3 groups listed in this way, and even more why their permissions are so different.
