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.

    I am totally new to phpbb but finally managed to work out how to change the file but I don’t get the notifications.
    Any idea what I’m doing wrong?

    I changed this, but the forum still has the check box unchecked. What do I have to do to “make it take”? (I’m very new to phpBB.)

    Try clearing your cache after performing this operation. Might help the changes take effect.
