Currently the Twitch implementation (plugin?) is not working. The way that Twitch handles embeds has been updated, so the way the URL is built needs to be adjusted.
Current implementation:
<iframe src="http://www.twatch.tv/GlovesOffGam..." frameborder="0" scrolling="no" height="280" width="500"></iframe>
​Needs to be:
<iframe src="https://player.twatch.tv/?channel..." scrolling="no" height="280" width="500"></iframe>
NOTE: I've changed "twitch" in the links above to "twatch" to avoid NA automatically rendering them as iframes.
