TOPIC: Registered users only see form??

I set up 2 forms, one for members and another for non members. I give the members a discount including the other sessions (discount only applies to the main rate, which is why I have 2)

So what I was wondering is how can I make the member registration page only show up when the member is logged in.

I can have the link only show up when a member is logged in, but the member can send the link around and give non-members the ability to sign in at the lower prices.

Other than setting the link to Registered in Joomla, there is no other check for this at this time.
