Do I need to use Buddypress to add user forms to my

Do I need to use Buddypress to add user forms to my subscription page? On my registration page it only shows a paypal button and says it's a free subscription. I want to have the name fields along with the email field but have no idea where I go to do this. Do you have any videos or examples of actually locking down a page that I can see? I've already watched the 17 videos you have on youtube but none of those videos actually show you how to add the codes and protect a page.

What I'm trying to set up is a customer portal (so the subscription is free) and when I try to lock down a specific pages with shortcodes it doesn't work. It appears that the short codes are not working. When I add the custom shortcodes to my post page [level-customer][/level-customer] it shows in the post as text. What am I doing wrong?
