+ Obfuscating E-mail Addresses
+
+ Do you ever wonder how your E-mail address gets on so many spam mailing
+ lists? One way spammers collect E-mail addresses is from web pages. To
+ help combat this problem, you can make your E-mail address show up in a
+ scrambled looking form in the HTML source, yet it it will look and work
+ correctly in the browser. This is done with the escape modifier.
+
+
+Example of Obfuscating an E-mail Address
+
+
+index.tpl
+---------
+
+Send inquiries to
+<a href="mailto:{$EmailAddress|escape:"hex"}>{$EmailAddress|escape:"hexentity"}</a>
+
+OUTPUT:
+
+Send inquiries to
+<a
+href="mailto:%62%6f%62%40%6d%65%2e%6e%65%74">bob@me.net</a>
+
+
+
+
+ Although this looks like a mess in the HTML source, it will render
+ correctly in your browser, and the mailto: hyperlink will go to the correct
+ address.
+
+
+ TECHNICAL NOTE: Of course this isn't 100% foolproof. Although highly unlikely, a
+ spammer could conceivably write his e-mail collecter to decode these
+ values.
