Email Address Encoder
Have you noticed that the amount of spam you get every day went up a notch when you started your web site? The reason is that spambots are busy harvesting site-based email addresses for spam lists. You can avoid this problem by posting an email "description" rather than an address - "send email to Susan @ HerDomain.com", but that's not particularly friendly to your visitors. A more useful approach is to create a snippet of code that looks and works like the address you need, but can't be harvested.

The Encoder we present below, authored by Dan Benjamin, is a great answer to this problem, using numerical equivalents to create a snippet of Javascript code you can simply cut and paste right into your web page.
