Protect your email inbox. Posting your email address on a website is the best way to get your Inbox full of unsolicited email advertisements. This application, for Windows, protects your email addresses by converting them into encoded JavaScript code, hiding them from email-harvesting robots while still allowing your visitors to email you from your web site. Just paste the JavaScript code block it creates into the HTML source of the website you're creating, in exactly the place where you'd like the address to appear. View the page in a web browser, and you'll see the link appear.
