"email AT address DOT com" (without quotes) is converted to a clickable version of email@address.com if JavaScript is enabled.

== Description ==

This email cloaking method: 

* is accessible for people browsing with screen readers (e.g., blind people); 
* degrades gracefully for browsers without JavaScript; 
* works just like a normal, clickable email address for browsers with JavaScript enabled; and
* requires no shortcodes.

Email addresses in the form `email AT address DOT com` are converted to a clickable version, [email@address.com](mailto:email@address.com), if JavaScript is enabled. If JavaScript is not enabled (such as for screen readers), then the email address in the form `email AT address DOT com` is still readable to humans.


== Installation ==

Unzip the zip file into the `/wp-content/plugins/` directory. Activate the plugin through the 'Plugins' menu in WordPress.

== Frequently Asked Questions ==

= Won't email scrapers figure out email addresses in the form `email AT address DOT com`? =

In a test comparing the [effectiveness of different obfuscation methods](http://techblog.tilllate.com/2008/07/20/ten-methods-to-obfuscate-e-mail-addresses-compared/) in 2008, the obfuscation method "Using ATs and DOTs" received much less spam than "Replacing @ and . with Entities". Assuming that the 2008 test is an accurate model, this plugin should reduce over 99% of spam without compromising accessibility.

"CSS display: none" should *not* be used, because screen readers cannot read content styled with `display: none` either. Reversing email addresses and using ROT-13 encryption are obviously not accessible, either.

= Do email addresses that end with ".ca" or ".info" work? =

Yes. Any email address with a TLD (top-level domain) of two, three, or four characters would work.

= Do email addresses that end with "co.uk" work? =

Yes. Email address that end in "co.uk" always worked, but as of version 3.2, you can use the intuitive form: email AT address DOT co.uk.

= Something is broken. =

Remember that the `AT` and `DOT` must be all uppercase (capital letters). You can also try going to Settings and change the replacement method to "Walk the DOM", which is the new default for version 3.0+.

If you still have problems, you can post your question in the [forum](http://wordpress.org/tags/humansnotbots?forum_id=10#postform) and make sure your post has the tag `humansnotbots`. Another option is to post your question [here](http://zingming.wordpress.com/wordpress-plugins/).

== Screenshots ==

1. Compose posts with email addresses in the form `email AT address DOT com`.
2. The post should show a clickable email address.
3. If you view the HTML source, the email scraping bots can only see `email AT address DOT com`.
