I have a script 'installed' on my website that I have used to obfuscate e-mail addresses on the websites I have created for others.

Note: j/s is required to run the script that encodes an email address, but j/s is not required on wherever the encoded link is to be displayed. For the ultra-paranoid, also note that the script itself can be d/l'ed and 'installed' and run from wherever you want, the script doesn't need to be run from my site.
