For Italian wikipedia, VisualEditor is active only in main and user namespaces.
The sandbox for new users is located at Wikipedia:Pagina delle prove in the Wikipedia namespace where VisualEditor is not active.
A WYSIWYG editor can be very useful for new users.
The solution to move the sandbox page in User namespace (like in English Wikipedia) is not the best way to solve this problem.
Maybe can be create a magic word for "activate VisualEditor for a single page" (instead of entire namespace), or at least making operable a link like this:
https://it.wikipedia.org/wiki/Wikipedia:Pagina_delle_prove?veaction=edit
Thanks!
