Thanks. By the way, I do not think that 1.75K is a small number. If you compare it against full-time RU-vidrs, it is of course small. But this channel is just a hobby and publishing the videos is kind of a byproduct of what I teach anyway in the class room. In this context I am really happy with the subscriber count. That being said, spread the word, hit the like button etc and help me to get to 10K! :)
