Adding a table to the ASPNETDB data base and editing the createuserwizard to collect and insert the data.

 Hi,
Mine is a tell-all-title.
I've created a new table within the aspnetdb.mdf database, which is related by UserID to the asp_membership table. I would like to edit the CreateUserWizard so that I can add extra asp:textboxes etc, and so that when the user clicks the 'create user' button the extra data is collected and added to the new table. (a big problem is that all of the wizard code-behind is hidden.)
 
Any ideas?
