Q180: Can I decide which administrative functions my resource administrators or moderators can access?

Yes, you can do this in Resource admin and moderator access permissions. You'll find this page in the site settings. Please note that by default both resource admins and moderators have access to all administrator pages. You need to specifically disable admin pages in order to limit their access.

checkin24-7 lets you create default perssions separately for the resource admins and for the moderators. On top of that you can also customize access permissions for each individual admin or moderator.
