I need a developer to help me out with mailchimp. My current email form (3 fields) is double opt-in (default) and I would like to make it single opt-in.
It can only be done if you use their API. Please see the link below:

Second task, if someone has already entered their email address, when they try accessing the page again, it should redirect them to a different page instead of displaying the form.
