Singed Copy of Electronic Tax Forms. How?

<p>I've been asked to submit signed copies of my 2009 tax return. I filed my taxes electronically and I have copies in .pdf format. The school has asked that I send these forms as an email attachment. How do I sign a digital copy?</p>

<p>Thank you!</p>

<p>I print out our copies, sign them and mail them to the school.</p>

<p>Print, sign, scan, email.</p>

<p>“Print, sign, scan, email.”</p>

<p>Genius! Thank you.</p>
