My desire is that everything on this website (except in the store) shall remain free of obligatory cost to all who visit.

I am also determined that the site shall remain advertising free.

Please donate as you are able and in a manner that you think is reasonable for what you have been able to obtain from my work.

Thank you very much for your support!

Your videos are awesome! And I do like when you refer to “top students” to talk about their behavior because it’s very encouraging! Thank you for sharing the knowledge!
