a computer expert one of you who could/would explain why the link in my upper post 'Tasso' created that false wikipage when I edited 'Tasso' to 'Link'.

You created a Wiki page on the Dutch version of Wikipedia. It's the nature of Wiki that if you link to a wiki page that does not exist, and then click on that link that it creates the page in question. I'm sure they'll delete when they see what you've done.

The text you typed in as the text article name was: "Link was a famous member of the Tassi, maybe distant, as he origins from the heel of the boot."

Ceci n'est pas un seing.
