Thanks.  I found the table.  I am used to being able to do something more with a form than just stick it all in the same place in a database.  I would have thought (and did) that when I specify, for example that a field that gets its data from Users.FirstName would store the changes in the place the data came from.  I need to create a registration form that will allow a person to subscribe to a paid security role, then make the security role assignment (or update the expiry date if they already have it) after PayPal processing.  I am not being cheap as much as I am trying to keep things from breaking during an upgrade when a third party module is no longer supported.
