Heya, I have finally added a guestbook for visitors wishing to leave comments. I use the Disqus service, which seems to be well accepted and functional. So, drop me a note, if you like. ☺

In addition, I worked on improving a number of pages... for example, the glossary has more entries now, and also more pictures. 

I guess I’ll take tomorrow off! ☺ Take care. 👋
