He shut it down a short while back due to lack of time. I cried for two days. :-(
I'm sorry for that :-)
The page is not completely dead though, you can still visit the old site on http://www.shmgo-zwolle.nl/spotmatic/index.html. But beware: it may or may not work well because the focus lies on the main site. But I've checked it and it's still there.
Depending on my time, I will probably bring the site back to life. Especially now that Spotmatics can be found so cheap...
Hope this helps,
