Oops, it looks like this site is a bit outdated...
What are you actually looking for?
original www.gerhards.net, historical page - no longer
maintained for quite a while
but definitely with very useful content. Just be prepared
for some really bad web design ;-)
Note well: this page is in archive mode. Dynamic functionality like forum or
comments are no longer working. Also, access counters and such are no longer
incremented.
