I’m sorry this site is just in English. To see only the videos, without text, grouped by topic, go to my Youtube channel.
(n.b: the videos do not convey all the information in the text, and some tutorials have no video.)
Todos los videos (sin texto) estan en mi pagina de Youtube.
Please help me out by leaving a note below, telling me how to write this in other languages (and correct my bad Spanish!)—Thanks!
