<h3>Shortcode settings</h3>
  <p>Shortcode: [easyicontact]</p>
  <p>Shortcode optons:<br />
  0 == false<br />
  1 == true</p>
  <ul>
    <li><strong>confirm_email</strong> (1 or 0) default: <em>true (1)</em></li>
    <li><strong>first_name</strong> (1 or 0) default: <em>true (1)</em></li>
    <li><strong>last_name</strong> (1 or 0) default: <em>true (1)</em></li>
    <!--<li><strong>table</strong> put the items in a table (1 or 0) default: <em>true (1)</em> NOTE: Not yet implemented</li>-->
    <li><strong>ajax</strong> (1 or 0) default: <em>true (1)</em> NOTE: while this setting is implemented, when not using AJAX to process requests, it may respond a bit strange. This feature may be removed in future versions.</li>
    <li><strong>validation</strong> (1 or 0) default: <em>true (1)</em></li>
    <li><strong>label_type</strong> ('label' or 'value') Create HTML labels or insert the lable as the default value of a field. If value is chosen, upon click, the default value is removed. default: <em>&quot;label&quot;</em></li>
    <li><strong>submit_image</strong> path/URL - If set to a value other than false, it will be used as the path/URL to a submit button image. Relative paths are relative from the <a href="http://codex.wordpress.org/Function_Reference/bloginfo" target="_blank">stylesheet_directory</a> (<em><?php bloginfo('stylesheet_directory'); ?></em>). Absolute paths and URLs are used as-is. URLs must begin with "http://" or "https://".  If submit_image is set, submit_text is used as the alt text. Default: <em>false (0)</em></li>
    <li><strong>submit_text</strong> text - Will show on the submit button if submit_image is false. If submit_image is used, submit_text is used as the alt text for submit_image. Default: &quot;Sign up!&quot;</li>
	<li><strong>callback_function</strong> function name - This JavaScript function will be called upon successful submit of the form. It is called immediately after the success message is displayed. Checks to make sure the function is defined.</li>
  </ul>
  <p>Example Shortcode:</p>
  <pre>[easyicontact confirm_email='0' last_name='0' 'submit_text='Sign me up!' label_type='value' ]</pre>
  <h3>Example CSS</h3>
  <p>You'll have to add this to your template's CSS file. In future versions, I may enable a custom CSS option, but for now you have to put it in your template's CSS file and edit there.</p>
