The Simple Twitch.TV Widget is exactly what the name implies. It is a very 
straight-forward, easy to use, and configurable front-end widget generator. 
The entirety of what the widget does, is show if a user is online or not. If the 
user in question is online, it will give a preview of their stream and a link 
to their stream. If they are offline, it will simply place a placeholder image 
there.
<h3>Support</h3>
I will provide ZERO support for this plugin. This plugin is being provided 
as-is, with no custom work for anyone. You may use at your own risk. 
With that said, if you find bugs you may report them to 
“judah@thosetechguys.org”. I will do my best to solve any problems with my work.
