How do I change the registration confirmation email to HTML from plain text? Also, where can I insert the HTML for this email? I searched the boards - but no luck. Any advise?
$lang_register_confirm_email in your language file is the place to start.
See in mailer.inc.php, declarationof cpg_mail function is :
function cpg_mail($to, $subject, $msg_body, $type = 'text/plain', $sender_name = '', $sender_email = '')
Maybe you can change the type there, and enter the html into the lang file, i havent tried it, but it may work.
