How does inviting your teachers to the Common App work?

<p>I've invited two of my teachers to use the Common App online. I typed in their names, listed them as teachers, checked the release box, but didn't type in their emails. Since the Common App knows my school, should they be getting emails soon regarding how to post their recommendation online?</p>

<p>No. If you invited them without supplying their email addresses, then commonapp.org considers them to be "offline" recommenders who will mail paper recommendations to your schools. If they prefer to post their recommendations online, then you'll need to delete them and re-invite them -- this time supplying their email addresses.</p>
