Email Link Encoder is a small freeware utility which will munge your email address so you can embed it safely on your website without fear of it being harvested by spammers. Very useful tool if you’re a web owner or blogger.
This antispam software utility enables you to encode your email links on your website so they can’t be extracted by rogue internet spiders looking for email addresses to add to junk mailing lists. This will help prevent you from getting huge amounts of spam.
Personally I prefer the free EmailMe form, I’ve used it on one of my sites and it is really neat.
