I am attempting to collection some information via forms (using WebForm) that are pre-populated using query string attributes. In order to access these forms users need to register an account or log in if you have already registered. After login/registration I need to send the user back to the Webform with all the query string parameters in place to pre-populate the form. Is there any way this can be done? I am currently using LoginToboggan, but I can't seem to get this to work quite right. Does anyone have any suggestions?
