If you have a live site that already has registered users, you will want to:
1. Update the program to have current dates and to be published (top left, toggle down from "draft").
2. Answer "yes" to the question, "Is this program only for staff members?" in program setup.
3. Login with volunteer access or above, scroll down and click on "View Reader Experience" at the footer of your page:
4. Make sure that your account has readers who qualify for the program you want to test (for example, if you have a program for 5-12 year-olds, you need a reader who is 5-12 years old to participate in the program)
