Friends & Contacts
Display your friend's most recent activities in a concise summary, with links to further explore and connect. Sort by Recently Updated, or Alphabetical.
Tip: you can also access your Friends' recent activities via the sidebar.
You can also manage your "Friend Requests" (Sent / Received) here.


- Import contacts from various popular address book programs / services.
- Contact List: organize your address book by creating and grouping your friends into Contact List(s).
Tip: you can treat your "Contact List" as an "ad-hoc group" whenever you need to share a bookmark or a message.
Friends' Bookmarks
One central place of all your friends' latest bookmarks and tagcloud in one place for you to view and enjoy them.

Find Friends
Not sure if your friend is already a Diigo member? Simply search your E-mail / Plaxo address book for friends or enter your friend's email on the bottom section.
Tip: if you encounter some difficulty connecting with your email, try to select "other" instead of specific email provider, and try again.

Our system will automatically identify their presence at Diigo:
- On Diigo: already a Diigo user. Select and click "Add to Friends", a friend request will be sent to them to their diigo account. Once they accept your friend request, they will show up on your Diigo friends list.
- Not on Diigo: not yet a Diigo user. Select and click "Add to Friends", an invite-to-join email will be sent to them. Once they have completed their sign-up, they will immediately show up on your Diigo friends list.
- Already my friends on Diigo: no action needed.
Invite Friends
You can easily invite your friends to Diigo by entering email(s), or look up your email address book. You can even send an invite message via IM to your IM buddies :-)
