I've just re-read what I'd said, you of course don't need to install PWS (or any other server) to edit and view web pages on your computer. I seem to be too fixed in the things I am looking to do at the moment. Still, PWS does give more scope for trying things at home. I use it for my test system.Again re-reading, for updating and changing, I use CuteFTP for transeferring files between my computer and my web space. It gives a Windows Explorer like interface and you can just drag and drop files from your web space to your computer or visa-versa. The only web based one I used was the one with my Tripod web space and I found it clumsly.
