What are Diigo Educator Accounts?

These are special premium accounts provided specifically to K-12 &
higher-ed educators. Once your Diigo Educator application is approved, your
account will be upgraded to have these additional features:

• You can create student accounts for an entire class with just a few clicks
  (and student email addresses are optional for account creation)
  
• Students of the same class are automatically set up as a Diigo group so they
  can start using all the benefits that a Diigo group provides, such as group
  bookmarks and annotations, and group
  
  
  forums.
  
  
• 
  Privacy settings of student
  accounts are pre-set so that only teachers
  and classmates can
  communicate with them.
  
• Ads presented to student account users are limited to education-related
  sponsors.
