<h4>Introduction</h4>
Chatster is a WooCommerce extension that allows real time chat with visiting users, supports your website growth with a BOT that will try to answer your customer questions and allows users to send messages and ask questions. 

The plugin is customizable, you can choose chat colors, bot image, screen position and much more.. Plenty of options are available for the front chat as well as the admin area.
The chat system will balance the load of customers across all admins that have selected to be online. 
You can select the maximum number of users you want to chat with simultaneously and Chatster will create a queue, inform the customers of their queue status and display in the admin chat the total number of user waiting. 
One of the cool features is the possibility to search product and pages without leaving conversation and attach them directly to the chat, where the customer can see and even follow the link.

The Bot helper will be your delegate when you are not around. You can program questions and answers. He will read the customer question, research the best match and pull the most appropriate answer. 
You can also adjust sensitivity and enable deep-search mode and personalize its responses.
If the customer requires a direct interaction and the chat is offline, the message me button is one click away. They can simply fill out the small form and send the question or comment through and it will be posted in the Chatster messaging section. 
Chatster can also alert you of new messages received, with an email sent to your favorite email address. You can then reply the message from Chatster and set up a reply-to email to continue the correspondence.

This plugin has two modes – basic and Akismet-enhanced.
Basic mode: the plugin will serve a CAPTCHA to all commenters that aren’t logged in and don’t have a previously approved comment. Repeat commenters will never see a CAPTCHA.
Akismet-enhanced mode (recommended): the plugin will serve a CAPTCHA only if Akismet identifies a comment as spam (much less frequently than the basic mode). Just install an activate <a href="https://wordpress.org/extend/plugins/akismet/" rel="ugc">Akismet</a> to enable this mode.
Note that a CAPTCHA will only appear after a comment is submitted. When a commenter is served a CAPTCHA:
<ul>
<li>If they fail, then the comment will be automatically discarded or trashed (and won’t clutter up your spam queue).</li>
<li>If they pass, it will be allowed into the spam queue (or approved, if you so choose). This means that any false positives from Akismet will be easily identified without you having to trawl through all the spam comments manually.</li>
</ul>
Most genuine commenters will be able to comment on your site hassle-free, without ever seeing a CAPTCHA.
The default CAPTCHA is a simple text-based test. There is also the option to use <a href="http://www.google.com/recaptcha" rel="nofollow ugc">reCAPTCHA</a> if you want something more robust (free API key required). You can also style the CAPTCHA page to fit with your own WordPress theme.
If you come across any bugs or have suggestions, please use the plugin support forum or <a href="http://rayofsolaris.net/contact/" rel="nofollow ugc">email me</a>. I can’t fix it if I don’t know it’s broken! Please check the <a href="https://wordpress.org/extend/plugins/wp-conditional-captcha/faq/" rel="ugc">FAQs</a> for common issues.
