The Elder Scrolls Online website announces that Bethesda is sending out a bunch of invitations to participate in this weekend's beta testing of The Elder Scrolls Online, and that these each will include an additional invite for a friend. Here's word:

Today, we’re sending out more beta invites for an ESO scale test. If you receive an invite, there will be an extra beta code included that you can give to a friend to join you in Tamriel!

For this beta, you are no longer required to follow a Nondisclosure Agreement (NDA). We invite you to post your best screenshots, videos, and impressions this weekend, and livestream your adventures for everyone to see. Be sure to use #esobeta to share your favorite moments with the world! Participants this weekend will also unlock an exclusive monkey vanity pet for PC/Mac that you can have at launch.

Thanks for your continued enthusiasm and support as we march toward launch. We look forward to seeing you in Tamriel this weekend!
