You can control who has access to your pages and collections. By default, only you can see your pages and collections. You can share your portfolios with the public, registered users, your institution(s), groups, or your friends. You can assign access to individual groups or users by using the options under "Share with" → "Search for...".
Access dates can be set, allowing you to make your page available for a specified period such as a course year, a project timeline, or even for one day only. All dates are optional. Individual users can be granted access by multiple access rules.
Example: Nigel is in the group "The Coolpeople's Club". If you allow him to access your page today and allow "The Coolpeople's Club" to access your page tomorrow, he will be able to access the page on both days.
