+FormSpamProtection 
+==================
+
+Tired of forms in your web application getting spammed? Captcha works but is a
+pain. This plugin ensures a real person is submitting the form without
+requiring anything from the user except that they have Javascript turned on.
+
+This plugin uses the Hivelogic Enkoder, normally used to protect spambots from
+harvesting e-mail addresses, to enkode a hidden field on the form. That field
+is required when the user submits the form or they get an error.
+
+To install: 
+  ./script/plugin install -x http://form-spam-protection.googlecode.com/svn/form_spam_protection/
+
+To use: In your controller, just add: 
+  protect_forms_from_spam
+
+You can also specify :only or :except just like a before filter:
+  protect_forms_from_spam :only => :index
+
+In fact, it is just a before filter. To protect only the form in one action
+and the handling (but not the form) in another, do this:
+  before_filter :protect_form_from_spam, :only => :new
+  before_filter :protect_form_handler_from_spam, :only => :create
+...though this is seldom necessary.
+
+Bugs:
+Please submit bugs through the tracker at http://code.google.com/p/form-spam-protection/issues/list
+
+TODO:
+* Add <noscript> tags to the form to display the "you must have Javascript on" message
+* Make messages and resubmit limit configurable

+==Hivelogic Enkoder
+
+The Enkoder plugin provides an extension to TextHelper that can be used to
+protect email addresses (or other information) by obfuscating them using
+JavaScript code. The only way to decrypt the JavaScript is to actually run it,
+hiding the results from email-harvesting robots while revealing them to real
+people.
+
+It uses a significantly different (and some might say more secure) algorithm
+than the built-in mail_to helper.
+
+Note: There's no guarantee here -- the only way to be completely safe is to not
+publish your address at all.
+
+
+==Installation:
+
+Just drop the "enkoder" folder into the /vendor/plugins folder in your project.
+
+
+==Usage:
+
+There are two methods:
+
+	enkode( html )
+	
+This method accepts a block of html (or any text) and returns an enkoded JavaScript.
+
+The second method is:
+
+	enkode_mail( email, link_text, title_text=nil, subject=nil )
+
+This method takes an email address, the text to show to the viewer, optional
+title text (what's seen when somebody hovers over the link), and optional
+subject for the email, and returns an enkoded email address link.
+
+
+==Examples:
+
+To enkode a single email address, one could just do:
+
+	<%= enkode_mail('user@domain.com','click here') %>
+
+And the following link would be returned (enkoded as JavaScript):
+
+	<a href="mailto:"user@domain.com" title="">click here</a>
+
+Adding a title and subject text would require the second two optional fields:
+
+	<%= enkode_mail('user@domain.com','click here', 'email me', 'enkoder') %>
+
+And we'd get back (enkoded as JavaScript):
+
+	<a href="mailto:"user@domain.com?subject=enkoder" title="email me">click here</a>
+
+Of course we can also enkode many email addresses on the fly:
+
+	<% @users.each do |user| %>
+		<p><%= enkode_mail(@user.email,@user.name) %></p>
+	<% end %>
+
+To enkode a snippet of XHTML, we can do:
+
+	<%= enkode("<p>This block will be hidden from spambots.</p>") %>
+
+We could protect a link or block of XHTML from being indexed like this:
+
+	<%= enkode('Try and find <a href="secret.html">this</a>, google!') %>
+
+We could have anything we wanted in that block, XHTML, links, email addresses, etc.
+
+For more examples and to see the full functionality of the Enkoder, have a look
+its permanent page on the web:
+
+	http://hivelogic.com/enkoder
