### Space Controllers
When assigning a User to a space you can optionally make the User a **Space Controller**

**Space Controller** is a special role that is assigned to an assigned space User.

A space controller can perform more actions in a Space compared to a normal user.
* Attach Space Files and pin the files to the Space Dashboard for all Space Users to access
* They are designated the 'go to' person for the Space and are listed on the Space Dashboard
* Manage Space settings from within the space (without being a system administrator)
