Winding down

A very quiet week, apart from the many blog posts, videos, new and updated modules :-). The nights are getting shorter again. Good news for many people in Ukraine who have no heating or water or electricity, and who are still fighting the Russian aggression. Слава Україні!  Героям слава!

Please keep staying safe, keep staying healthy, and keep up the good work!

If you like what I’m doing, committing to a small sponsorship would mean a great deal!
