It seems, my example in my sandbox is working again. I'll ask around if it works for the others as well

After my table stopped floating right:

{| class="wikitable floatright mw-collapsible mw-collapsed" style="width:20em"

Funny thing....
When I went to change the setting here in Phab, I could choose Iso, US or Europe.
Which also sounds more logical to me.

I use British English as that's the language I communicate in through my global preferences on several wiki's, and I often take screenshots for explaining things, or explain where people can find this or that.

I would have liked to, to continue. But due differences of opinion, the Danish Wikipedia colleagues have worked against almost everything, and finally banned me outright, as well as the admin who supported me. So eventhough I would like to, I can't.
For the Danish Wikipedia people it's more important to keep things as they were, as "we always have done." It's the Danish culture, to go against everything progressive. So I will resign this project, but I hope that someone else will take this up, as Holland is not the country, which it isn't in any of the other Scandinavian languages either.
