Separate Registration Forms For Different Types Of Users

Hi,

Is it possible to have separate registration processes for different types of users?

Here is what I would like to do:

Certain people from one of my email lists autoresponders (List A) get a special rebate at a certain point in their journey, while all others always pay the full price.

Members of List A would be send to a different landing page, where they could register for the rebated membership.

All others would come through the normal registration form offering all other memberships.

Is this possible?

Jonathan
