I have been using Web Studio, for awhile, works great, you do not need to know html,
Its is up loadable to most hosing sites, drag and drop for the most part, easy to catch on to use. Works great! Of course you have to make the site your self, but it’s easy to do, and vary easy to update when you make changes, one click of a button in fact.
