New Registration Landing Page

[starkite]

Hi,

I'm currently using virtuemart in it's catalogue form, but I am still using virtuemart's user registration so to collect applications for people who want to receive promotional emails and the like.  However, I want any new registrations to hit a particular landing page once the form has been submitted.

Its pretty confusing as it is now, that people see "Account Information" or "Billing Information" when that isn't really what the form was for - instead, I'd prefer those who register to land on a welcome page that thanks them for sending us their information and gives them details on how to go forward ordering from our company.  I have such a page built, but there is no option to change the landing page for new registrations. 

What file on the server can I alter to change the landing page?  I've found it very hard to weed through the many PHP files associated with virtuemart to find the code that declares the landing page.

Can anyone help me with this?  I'd appreciate it.  Thanks!
