The Email Protector Plug-in is a Joomla! 1.5 plug-in that hides the email addresses on your web site from robots that collect them and send spam. It has the same purpose as the core Joomla content plug-in that comes with the installation of Joomla. Of course, there are some differences.
Unlike the core Joomla email cloak plug-in, ours handles the whole page, not only articles. This allows you to have email addresses everywhere in the page without worrying, for example, in Custom HTML module.
Finally, we have a different way of cloaking emails than the standard Joomla plug-in. Ours is probably not better, it is just different.
