doc.jspwiki.org is unreachable, yet it's where all the documentation links are pointing to.
The domain name is simply unknown in DNS:

Note that I'm asking ns2.surfnet.nl, the server who holds authority for the jspwiki.org domain.
If he doesn't know where doc.jspwiki.org is, it's hardly a surprise that it doesn't work
Could somebody please look into the DNS configuration, or maybe give us an idea of a mirror, or alternative way to reach the documentation for the time being.
Please forgive me if this is the wrong place to report this. I am new to this project (hence my need for documentation) and hate to be a PITA from the start
