Defeat spam
I've just learned a trick to cheat the robots scouring the web for email-adresses for spam advertising.
In stead of writing your actual email adress in the HTML source code of your webpage, you write the ISO equivalents. An a, for example, is &97; (the rest of the alphabet is the following numbers), the @-sign is &97; and the . is &46;.
The spam robots don't understand these codes - whict means they don't recognize the email-adress. The web browser, however, renders the page as if it was written with normal letters. Clever. :-)
