What do I add to the protected page

Hello,

I think I have almost everything figured out on the site except 2 things.

1. What to add to a protected page. There is a forum page and that is the only page that you have to be a member to view. What do I add to the page so that you can't view it unless you paid the membership?

2. The form shows up to become a member but the payment option to join doesn't show on the form. I need it to be setup that you have to pay 9.99 a year to view/participate on the forum page.

Thank you!
Peggy
