Not displaying your Email online is one of the basic steps to avoid spam. To avoid spam you have to create an image of your email, just like your Facebook does.
The image url of your email on Facebook is:
http://www.facebook.com/string_image.php?ct=…&fp=8.7
The number at the end (8.7) adjusts the font size, increase the number and you will see a bigger picture of your email.
Now use the URL to share your email address in a safe and free from spam way.
