Link anonymous to personalised survey
I need to create one survey (Registration site) which is an anonymous link that can be distributed to potential respondents who will be given a brief introduction to the survey content and if willing to participate will enter some basic info, name, email, organisation etc. On providing this information it will be passed to second survey (Main survey) to generate them a personalised link. Ideally the link will be displayed on the 'Registration site' and also sent to the email which they have provided on the previous page.
What is the best approach to accomplish this?
All help greatly appreciated!
