Until recently, we recommended Contribute from Adobe to our customers who wanted to maintain their own sites.
The program lets you open your pages, make changes, and save them for later or post them to your live website. You don’t have to look at the code (HTML)–it’s more like working in Microsoft Word than Dreamweaver.
However, Contribute isn’t available under Windows 8 and Adobe doesn’t seem to be interested in updating and maintaining the program.
Our current recommendation is a free program from Microsoft, Microsoft Expression. It looks more techie than Contribute, but you can ignore the code parts and just work on your pages. You can download it at Microsoft Expression Web 4.
