Help pages won't be overwritten if one of the same name is created on Community Central. The information from the page on Community Central will be transposed under whatever content is put on the help page created on the original wiki, in this case Art Wiki, unless __NOSHAREDHELP__ is put somewhere on the page. This means you can make help content specific to your wiki on any topic with any page name in the Help: namespace. The Project: namespace (the one which is named after your wiki) is better for things such as policies etc. rather than help pages because if all help pages are in the same namespace you can easily make lists of all help pages either by doing a namespace specific search in special:allpage or by using DPL (if DPL is enabled on your wiki).
