Subscribe page

I have added the html code to subscribe to a mailing list to a page on my site http://ivanhoecycles.com.au/mail.php . It redirects to /users_login.php instead of /subscribe.php.
What I am looking to do is simply collect the email address from the user. If this is not possible Im happy to write the INSERT code separately.

The user must be logged in before they can subscribe to a mailing.

they would need to create an account using the Registration page, the login.

If they are not logged in already, they are directed to the login page, the login page contains a link to the registration page.

Ok thanks for that - I understand.

That sounds like too many steps to get someone on the mailing list to me. There is no reason writing new subscribe and unsubscribe pages without the need for a login will effect the mailing is there?

yes, this could effect the mailing.

when crating a message, there are various tokens that can be used to add user attributes to the message like user first name or last name.

If the user has not gone through the registration process, these values may not be present.

also, when creating a mailing group, you use those user attributes to include specific user, those wont be available without the user having registered in the system.
