In SharePoint 2010, access is controlled through a role-based system that uses permission levels. Permission levels specify what permissions users have on a SharePoint site. These permissions determine the specific actions that users can perform on the site; in essence, each permission level is a collection of permissions. SharePoint Foundation has five default permission levels:
Read – This permission level gives you read-only access to the website.
Contribute – In addition to all the permissions included in the Read permission level, the Contribute permission level allows you to create and edit items in existing lists and document libraries
Design – In addition to all the permissions included in the Contribute permission level, the Design permission level allows you to create lists and document libraries, approve items, and edit pages
Full Control – This permission level gives you full control.
When you sign-up for a free trial with SharePoint Hoster, we will provision your site and create 1 admin (Full-Control) user from the provided email address. This initial account has the power to create additional users and set permission levels. You can invite anyone to your SharePoint site since we support automatic user creations and external users. You set their permission level and you’re off collaborating in the cloud!
