Machinery4change.org has been built using Sitespinner Pro. This is a very easy to use program. Any problems found will usually be caused by me. The program is capable of building a far more sophisticated site than this, but I chose to keep it simple, with fonts and colors to suit my taste. Provision is included in Sitespinner Pro to create a dual desktop or mobile sized display. I chose to make only the desktop size, but screen resolutions have changed over the years and the display now seems Ok even on a 7" Android tablet.
