I maintain a number of webpages in beta phase, unlaunched. These are works in progress that nobody else should see. But sometimes I accidentally link to these pages from other pages, as if they were finished and already launched. So when I am working on a new page, my Content Management program, Ziggy, automatically creates a redirect page that points here, in case I accidentally link to the page in progress.
So if you see this page, please accept my apologies, but you have clicked on a link to a page that I have not yet launched! Just use the back button to go back to the page you were just on, and try to hide your disappointment!
Pages can remain in beta for days, weeks, months, or even years, until I have finished the page, so, it is probably not worth re-trying the link, at the moment.
Check "Vexen Crabtree's Websites: What's New and Site History" by Vexen Crabtree to see what new pages I launch.
