Did you accidentally import a bunch of commitments and forget to enable the reminder notification?
You can now edit multiple commitments at once to enable (or disable) the reminder notification.
First, go to Admin » Commitments and either (a) filter the list of commitments or (b) select the checkboxes next to the commitments you wish to edit.
Then, click the Edit Commitments button.
Finally, make the desired changes and click Save.
All done!
