Waaaay at the bottom of the screen is a widget for chat.

This is based on the following HTML which is included in the template for my website:

<!--START Chat Widget -->
<!--If you already have jquery on the page you don't need to insert this script tag-->
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js" type="text/javascript"></script>

<link href="https://d218iqt4mo6adh.cloudfront.net/assets/widget_embed_191.css" media="screen" rel="stylesheet" type="text/css" />
<!--If you already have fancybox on the page this script tag should be omitted-->
<script src="https://d218iqt4mo6adh.cloudfront.net/assets/widget_embed_libraries_191.js" type="text/javascript"></script>

What I would like to do is make this hover at the bottom of the page. I'm not sure if "hover" is the correct term. The idea is you shouldn't need to scroll to the bottom to see it. It should always be there.

Also I would prefer it to be bottom-right instead of bottom-left.

Any suggestions?
