Here you can see which part of my website was updated in the
last time
(new things on top of the page)
Important: The date given is the date I updated the files
on my HDD, NOT the date I uploaded the files onto the server.
Usually, these dates are the same, but sometimes there will be a delay (I'm
to lazy to upload every minor change immediately)!
| Ever wanted to know how it all started with my website?
If you REALLY feel curious, you can look at some old versions which have
been archived by "The Wayback Machine" at
http://archive.org.
It offers billions of old websites and even most
of the graphics. But it's not searchable. You
have to know the URL of the old site. Here comes the one to my old
pages:
http://web.archive.org/web/19990101-20010131*/http://privat.schlund.de/s/skluge/toc.htm That works only with my old pages from Oct. 1999 until February 2001 (I don't know why the very old pages from 09. Dec. 1997 till Sept. 1999 are not archived there..), because Terry, who kindly hosts my site since the old provider shut down the free hosting business, has placed a robots.txt file in his root directory to prevent lots of spiders consuming to much bandwith. But that's not really a problem, the currrent version of my website is the best ever anyway ;-) |

| 10'00 | 2"-system | The good lifetime of all the MMCs buildt by many people let me think a bit more positive on the design of a new MMC for my 2"-system. I will try to use less caps per string in the MMC for the 2"-system. Stay tuned on this page! |
