What it boils down to is you can add additional pages if you set the pages as content management templates when you are creating the site. These newly created pages will not be included in the menu structure but you can internally link to them.
If you want a new page its suggested that its easier to just recreate the site which is not too hard if you set your presets so you do not need to select all options.
But I would imagine you would lose all your content by doing this? There was no mention of that or how you could recreate the site so you can add pages and yet not lose all your site content.
There is that post above concerning manually adding and deleting pages but that seems a lot of work. It would seem that this product is for setting up very simple web sites that dont change a lot where you can give the end users the ability to update their own content without needing dreamweaver, etc.
It would seem that the power cms 2 product is the way to go but its only licensed per domain and I want this for setting up many domains for other people so the site scluptor seems a better fit. So I will continue playing with this and in a bit start playing with manually adding and deleting pages. I can guarantee you that if you set one of these sites up for a client they will want additional pages and they will want items added to the menu structure. Thats a given. If this product could do that then it would be the great product I really think it can be. Site scluptor will allow people with no coding ability to run a website and will be easy to use. For the webmaster it will be a headache I am thinking. Automated for the end user - everything manual for the webmaster. Of course maybe I am missing something as I said about recreatig the site locally using site scluptor - uploading it again - and yet not losing all the content already on the live site? Perhaps you need the local test database setup?

Neil's response really cleared up things for me.
Hope that helps.
