inSSIDer Video Issue

I would like to say that i am taking a class in Syber Security and one of the assignments was to go to your website. Looks really cool! the only thing I would say is that the video describing how inSSIDer works was not in CC. My computer in my class does not have audio, so it would be cool if CC was an option. This would also be good for people who are hard of hearing. Going to look more at the website later:)
