When adding users to RogerRoger, you can give them roles that provide them with specific permissions. When creating a RogerRoger account, you will automatically be granted the role of admin.
An Admin:
Contacts: You have the ability to add and manage contacts.
Workspaces: You can create a new workspace and manage your own workspace. You still have the authority to manage other workspaces when you're not the owner.
Tags: You can manage tags.
Email: You have the authority to add and modify your own mailbox. This also applies when you're not the owner of the mailbox.
Other: You have special permissions to add, edit, and remove users and to manage subscriptions.
A Manager:
Contacts: You can add and manage contacts just like an admin.
Workspaces: You can add a workspace and manage your own workspace. You can still manage other workspaces but only columns when you're not the owner.
Tags: You can manage tags.
Email: You are allowed to add a mailbox and make modifications to your own mailbox, even when you're not the owner.
Other: You can add and edit users only when you're the owner.
A User:
Contacts: You can add and manage contacts in your account.
Workspaces: You can create a new workspace and manage your own workspace. However, you don't have management rights over other workspaces when you're not the owner.
Email: You can add a new mailbox and edit your current mailbox, but you can't edit other mailboxes when you're not the owner.
How about my mailbox?
Each user can add a mailbox (depending on the subscription and available channels), which can only be managed by the user. So, no other users (even the admin) can see or change the permissions of the mailbox(es) you connected to RogerRoger.
