Reposting my League forums post in case you didn't see it there.
Currently broken, it just says "no data available in table". I think it's because CLG changed the url for the streams ie it used to be "http://clgaming.net/live/5" but now it's "http://clgaming.net/live/29454-chausterlol". Seems like it'd be an easy thing to fix.
This is a great app that features a nice drop down menu that enables users to access virtually all League of Legends live streams. It lets you mark your favorite streams and notifies when they come online with a little pop-up message in your browser (it's unobtrusive). All streams are hosted by own3d.tv, the go-to website for streaming League of Legends, and the links from the plug-in lead you to clgaming.net, where these streams are featured.
