Turn on Topic Reply Notification by default in phpBB

In phpBB3, topic reply notification is set to “Off” by default. Unlike vBulletin, where you are automatically subscribed to threads which you reply to, in phpBB, you have to manually check “Notify me when a reply is posted” from the “Post reply” page to subscribe.

However, there is an easy file edit that will keep “Notify me when a reply is posted” checked by default when posting a reply.

Open ‘includes/functions_user.php’:

Find :

      'user_notify'         => 0,

Replace with :

      'user_notify'         => 1,

After this edit, users will be automatically subscribed to threads while replying.
