Help drive traffic back into your phpbb forum by defaulting the notify me option on members posts to YES. This will ensure the member gets an email when someone replies to there post when they may usually forget to tick this option. They will of course still have the option to un-tick instead.
Edit the Functions_user.php file as follows
‘user_notify’ => 0,
‘user_notify’ => 1,
To update all existing users run the following in MySQL PHPadmin
Sql statement - UPDATE phpbb_users SET user_notify = 1 WHERE user_id > 1;
