I'm not a SQL guru but know how to run a script from the admin panel for the database. Since there is no admin screen to set default preferences, can someone please post SQL scripts I can run as admin that will do the following?

1. Set the answer to "Yes" for all users "Do you want to be notified via email when you receive a private message?"

2. Set the answer to "Yes" for all users "Accept private messages from other users?"

Is there a mod I can do so all new users default to these answers? I'm running version 7.5.4.1
