Hey @matkodurko! thanks for stopping by and your feedback ! .. well .. on the Dtube thing it basically comes down that it never uploads for me.. and then I can't watch the videos at all.. so it comes down to practicality , also the fact that it gets taken down after a period of time makes the blog more difficult to compile.. since I use my lessons here to send to students outside the blockchain.. I can just address them to a particular lesson and if the video is lost.. it becomes messy , that is basically it.

and hey! big props on your school project! I work with kids myself and it is very rewarding .. plus i'm a big supporter of musical education in children ! happy to hear that you are venturing there. Cheers!
