Within the context of the mojoPortal CMS, Artisteer is only a tool used to create skins to change the look and feel of the site, not to create site content. In other words, the content you see while designing in Artisteer is just for demonstration purposes. If you want to use Artisteer to create and maintain actual HTML pages, and upload those pages to become an HTML site, you should probably ask any questions about doing that on the Artisteer forum.
I hope that makes sense.
