UPDATE: THE VIDEOS ARE BACK ONLINE. YOU CAN IGNORE THIS POST NOW. If you take a look down toward the bottom of the home page, you may notice that the section displaying videos has been removed. This is only temporary – for several hours, there has been a problem with the videos loading, which slows down the loading of the rest of the page, including elements in the right-hand navigation bar. In order to make the page load more easily, we have pulled the videos down for now, but we are certain they will be back up soon. Sorry for any inconvenience.
