The Docwiki site is now accessible here:
http://www.docwiki.net/

I got a better deal from my Webhoster, so i decided to use a seperate domain for docwiki hosting. I'm currently a bit busy studying computer science at the TUM (Munich), but i'm going to do some work on the docwiki again in the next few weeks - and the next term break isn't too far in the future, too :)
