When doing a signature for your email. How can you change the font other than what is on your email?

The font on your email only give you approx. 8 or 10 choices, I want to change it to something like handwriting not printing.|||Use any drawing software like %26#039;Corel Draw%26#039; or even %26#039;windows paint brush%26#039; to draw your name by mouse-dragging or movement with your hand that will be more like your OWN!
