CHP 3, like all the Claris applications, is very capable for its size and so easy to use that it is hard to beat it for its intended purposes. These purposes are limited, undoubtedly (e.g., no cascading stylesheet support), but for what these forums are meant to represent (and sadly falling away from of late), the fact that it works on 68k as well as ppc hardware is a bonus. It has typical Claris user-friendly touches like automatic conversion of imported graphics like PICT or a TIFF to GIF (the right format for the web). It is genuinely WYSIWYG and can be controlled through the standard Macintosh GUI, as you would expect. CHP3 will also work seamlessly with Filemaker version 4 if you want to use the latter to generate a database-driven, low-tech "dynamic" site, or to include such content in a frame.
LowEndMac is still produced, from what i can gather, on CHP3, so that will give you an idea of what the program can do, though I find LEM's design rather poor, and as such, it scarcely represents an ideal commendation.
One point that I would make is the CHP's built-in templates are, one and all, rather cheesy and very, very 90s in look and feel. If you want to see the program at its best, design something with a custom look. It is easily done. I once ran a website which had a series of images from the Musée Louvre as a theme (the Louvre has made a range of art available in the public domain). Text written in ClarisDraw and saved as GIF files served as image-mapped links (these may have taken longer to load but were also much easier on the eye than the standard blue underlined text). It was very easily done. At one stage, I tried to replicate the design in Adobe GoLive to see if it could do better, but gave up after a couple of hours because of the learning curve.
I went to the length of buying the manual, but there is a good CHP tutorial sequence at
www.easygreen.net/design/lessons . Several others are out there, often intended for an educational audience where, it seems, the program had an avid following.
