As a possible simple workaround for tracking affiliates, could the following be implement easily?: 1. Add an affiliate ID to the query string on linking to amember (or default to the referral URL) 2. Start the PHP session. (or create cookie) 3. Redirect browser to specified Web page 4. Store the affiliate ID or referral URL in an optional custom field when the customer signs up. 5. Ideally, provide an option to Report or sign-ups sorted by referral ID. Eg: www.mydomain.com/amember/track.php?affiliateID=321&redirection=/index.php Regards, Ian Tresman, Web publisher, Knowledge Computing 33 Reginald Street, Derby DE23 8FR Tel: 01332 265566. email: ian@knowledge.co.uk Fax: 0870 167 1951. http://www.knowledge.co.uk
