Just a hoax?

[Jorge_Stolfi]

Actually I write about all this stuff in my work. I encourage you to read it "from board to board"

Will do! But the link in your profile is broken. What is the best pair of boards?

Actually many of them may come from some 19th century school teacher.

I barely missed having Latin in high school, but colleagues a bit older than me used to say "tintinnabulus sonabit" for "the bell is ringing" -- a joke that apparently started in their Latin classes, when the school bell rang...

All the best, --stolfi

PS. Since your user name is just "Rafal" and you are here in the Voynich playpen, I always assumed that you were Rafal Prinke, which I knew from the old Voynich mailing list days.  But now I see you are not, correct?
