EMC2 Popup Disclaimer uses Fancybox (http://fancybox.net) to display the popup, and jQuery-cookie (https://github.com/carhartl/jquery-cookie) to detect user session. Creates a cookie named “emc2pdc” that can be viewed with regular developer tools.
Easy to use! By default the script is added to the wp_footer action and will work quietly. You can also force the display on pages via shortcode or function call: 
Shortcode: <code>[emc2pdc id="42"]</code> 
 -or- 
Function: <code><?php emc2pdc_force( $atts=array(), $force=NULL, $id=NULL ); ?></code>

To Do list:
<ul>
<li>Add No-JS fallback support</li>
<li>Create a selection of button themes</li>
<li>Add support for different lightbox types</li>
<li>Improve handling, add PHP cookie support</li>
</ul>
Known bugs:
<ul>
<li>Recursive post shortcode call results in chaos</li>
</ul>
<h3>Configuration</h3>
EMC2 Popup Disclaimer will work straight out of the box. There’s a few options available from within WordPress, and future releases will feature themeable options.
Settings can be found in these locations:
<ul>
<li>/wp-admin/options-general.php?page=emc2-popup-disclaimer/emc2pdc-admin.php (Default settings)</li>
<li>/wp-content/plugins/emc2-popup-disclaimer/js/emc2pdc.js (Fancybox, jQuery-cookie settings)</li>
</ul>
The settings page is straightforward except for perhaps the “Restrict operation to directory:” setting. This is the operational directory of the jQuery cookie plugin – default is ‘/’, which is your entire site. To specify operation for a certain directory, type it here like ‘/store’. More jQuery-cookie settings can be found at https://github.com/carhartl/jquery-cookie.
Things of note:
<ul>
<li>Specify post ID using shortcode is optional ? if blank, it will use ID# from settings</li>
<li>Shortcode / function call will override wp_footer action</li>
<li>Debug mode will output visible settings on every included page</li>
<li>Setting an ID equal to the page you?re calling from results in mass chaos! If you set the shortcode [ emc2pdc id=”10″ ] on post ID 10 it seems to freak out a bit.</li>
</ul>

This plugin allows you to add custom agreement selectable checkboxes to the Registration Form of your online store. You can define which checkboxes are mandatory to be checked/selected in order to register a new account. The plugin features also a double password validation, which adds an extra field that prompts an User to repeat his/her password.
Already registered users can see the form right underneath their “account details” and the plugin forces them to check the mandatory checkboxes as well upon saving their details.
! IMPORTANT: in order to use this plugin, you must enable “Allow customers to create an account on the “My account” page” 
in WooCommerce > Settings > Accounts & Privacy
Stay tuned for the payable, fully automatic version of this very plugin. See screenshots 10 and 11.
