How do you modify existing pages?
 On the manage pages tab, in the Configure fields section, select the email address column and check the "Validate unique Column value" option

I've run into 2 problems.  I have added the validate unique value and re-run the create pages wizard for the Administrate users.  The first problem is that the search form now requires an email address, which I don't want to require for search, only for inserting new person, just to check for unique value. 
The second, on another set of previously created pages, I have a registration form, but I don't see a way to modify the existing pages to add the unique validation to it because there doesn't seem to ba an update pages option in the manage pages. When I try to select pages to modify, the option is greyed out.
