Sue: As I had been able to access the new Family Search site, register and make searches, I decided to ask them if you had to be a LDS church member. The reply I received today indicates that anyone can join. Here is a copy of their email to me:

"No the site is free to all. The reasons for registration are to limit the number of people who can get on at any one time (because we have the site on computers which cannot handle large numbers yet) and to have a record of users so that we can communicate with them easily. The site, at present, is considered to be a pilot, as we are testing means of data presentation, etc, asking for feedback from users on what they like and do not like. Eventually the site will be launched for general use, and registration will be eliminated.
Thank you for your feedback.
Sincerely
FamilySearch Indexing Support
