Here is the letter inviting people to participate:
Dear LDS Church Members and Friends,
The Church of Jesus Christ of Latter-day Saints is developing a new version of the FamilySearch.org website. This new website will help members identify ancestors, link them to families, and provide temple ordinances for them.
Can you volunteer an hour of time to help evaluate this new website? Do you know someone else who might be interested? We need feedback to make the final website as easy and enjoyable to use as possible. We are especially interested in feedback from individuals who are new to family history work.
Anyone over age 18 interested in participating in this evaluation should go to:

Thank you for your interest and enthusiasm. We greatly value your time and opinion.
Sincerely,
FamilySearch Evaluation Team
Family and Church History Department
The Church of Jesus Christ of Latter-day Saints
