However, By doing this you lose the ability to click on the name and have an email client open up and create a new message with that address in the to: field.
Also, while this method may trick some automated scripts, it is a very trivial system to beat. mart wrote a small perl snippet that extarcted the email address from the page in 8 lines of perl.
It gives the user the option to click on the address and create a new message to the person. Plus, it the email address is not on the same line, so it adds another "level of protection"
I have tested it and it works quite nice
