Custom Registration Page and Listing of Registrations

I want a custom page that lists meetings that say "Register" as you can see on this page: [login to view URL] The purpose is to be able to track what custom link was used to come to the registration page. Links like [login to view URL] could be used to generate the tracking code. I want another page where the customer can enter in the tracking codes being used and a plain text description for the code. The customer should be asked to enter in a name for the code and the custom link should be generated for them so that they can use it in the invitations and website. This page should also then list those that have register by name and other info they provided when they signed up as well as what tracking link they came from if any.
