Chess expert, shogi 2-Dan (81Dojo), Riichi City 1st Dan, amateur OMGWords player, and Lichess & Lishogi developer. I stream using Chatty, and use Open Font License fonts, with thanks to the Free Software Foundation.


The main reason I applied for Affiliate status was to grant you, the viewer, transcoding (quality) options. I make a living developing and testing software; in my free time I collaborate with free software developers. In my wildest dreams I would teach (civics & philosophy, science & technology) and play board games & music 24/7. My friendship and integrity are never for sale--my opinions are my own--and I encourage supporting experts who I host, although I do humbly accept your support in case there is merit to that dream. A word to the wise: if you want me to host you, from time to time try watching your own content. Please don't pirate music; it's your fault musicians have a difficult life.
