How should I submit the extra teacher recommendation?

<p>I asked for an interview at Bowdoin but because they had no alumni in my area, they said that I could submit an extra teacher recommendation. However, the common application online only allows 2 recommenders to be assigned. Is there a way for me to submit the extra teacher recommendation online, or should I just mail it to them? (I live abroad, so online sending is highly preferable)
Thanks for any help on this!! (:</p>

<p>No way to do it online. Other than hard copy, how about explaining your situation to Bowdoin and asking if your recommender can email it directly to them?</p>
