Thread:Extension talk:Echo/How to disable the "page linked" notification generated by Echo?/reply

Just looking over the code in Echo.php i believe the two relevant options are:

$wgDefaultUserOptions['echo-subscriptions-email-article-linked'] = false; $wgDefaultUserOptions['echo-subscriptions-web-article-linked'] = false;

It looks like the default value is false for both of those, email because all emails default to off, and web because there is a specific override in place in the Echo.php file.
