In order to work, we have to insert at the top of existing (English) pages :
[[include include:languages pagename=NewPageNameHerePlease]]
with the NewPageNameHerePlease replaced by the PageName of the current page.
This sticky is temporary … for cut & paste purposes. Once we have finished the window dressing, a few hours (?), I (we) will remove this or replace by an invitation for more languages… Who knows?
Have you ever tried the updated newpage button at the botton of the side menu ?
It will create a newpage based on the template:languages which will insert the
[[include include:languages pagename=NewPageNameHerePlease]] sentence.
Before saving the new page, again NewPageNameHerePlease has to be replaced by the PageName of the current being crated page.
