This plugin extends functionality of listed items. As an administrator of your directory site, you can allow your users to claim existing listed items if they are their owners. Then the user, owner of listed company or etc., can administer his item presentation and update its information on his own. Simple as that.
Directory+ theme is tested & fully compatible with this extension plugin. This plugin is not required for your website to function and only needed if you require the additional functionality provided. This plugin is not bundled with the theme.
