Thread:Project:Support desk/How to create Help: pages in my wiki?

I'm creating a wiki about the WWII here: http://wikimemoria.weboil.it It's localized in italian language. In "navigation" box on the left there's a link to help pages ("Aiuto"). Following the link i reach the page http://wikimemoria.weboil.it/anpi/Aiuto:Indice (i suppose "Help:Index" in english language). The page is empty, I cannot create or edit any Aiuto:_something_ page even if logged in as WikiSysop. The error message says I don't have permissions to create that page. I would like to use the Aiuto: (Help:) pages to give information about formatting text, upload images and so on. I need help to create the help pages, I found no help page concerning help pages. Please help :)

Thanks in advance.
