JamesDBartlett3, 
I've been really enjoying #MSBuild so far, but the #chatroom next to the #streaming video is extremely distracting, so I wrote a #UserStyle #css that hides the #chat and resizes the video to take advantage of the extra space. Just install the #Stylus browser extension (https://add0n.com/stylus.html), then click the Install button on the linked page below, and enjoy a cleaner, less distracting #MicrosoftBuild experience. 😎
