Keith, the video is just what was needed! It's going to be very helpful to users. I linked it from the first post.
P.S. I enjoyed seeing how fast the file downloaded on your computer. Now .zip, .stt, and other attached files are being served via CDN (Content Delivery Network). The good thing is it speeds up the download, but there's a negative aspect to it, too. The "views" counters no longer reflect the real number of downloads because the downloads no longer go via the site's own server but rather they are being served by the CDN's edge server closest to the user. So there may be hundreds or thousands of downloads of a file, but the "views" (download) counter may not register them at all. (I'm considering removing the "views" counter).
