Viewing custom fields registration form

Hi Nicolas,
I've create a custom field type "address" to include in the registration form. It's basically a "where did you find us?" question for the client's information.
I'm now looking at how they can view the data in the backend. I've realized a custom field type "user" can display as a new column in the user list which is awesome, but how do I get it in the front end registration form. Am I on the right track?

Thanks heaps,
Chris

haha, thought I had that ticked, thanks for your prompt as always support!
