I want to divert all non-logged in members to the login page straight away, and not to any other page. The site will be invisible unless logged in. Currently they get shown the 'membership options page', exactly as per the documentation. I want the page to be shown to be the wp-login.php page.
The members get to be added to the site from a purchase on another specific sales page (on another site)using the API calls.
Is this possible as I cannot find anyway/anyone who has done this?
