Everyday I get at least several emails sent by YouTube advising that someone has subscribed to the UA's channel. I often click the text link to retrieve the new subscribers YouTube page and 9 times out of 10 it's either a porno site, some commercial site, or a site that defies description. People notify you of their subscription just to get you to look at their YouTube channel.
Once in a while I will see one that seems to be legitimate. Today, the third subscription notice (it is only 08:55 after all) is from someone in S. Korea who lists his/her age as 20 years old. There is no content but what this person is using YouTube for is to track different US colleges. Perhaps this person is interested in US universities with English as a Second Language programs and found the UA CESL's videos on YouTube. Perhaps he/she is looking for excellent science programs. In any case, he/she is examining the UA through the videos we have on our channel.
Here are some screenshots to step you through what I've seen.

Indeed, YouTube is providing a valuable service to prospective students. How much more informative it is for prospective students to be able to see "more" of the UA through the various videos instead of reading text on a page. There is some good news out there! Thanks for sharing.
