Darren, sorry for the delay... been under the weather and then just
realized no one else posted yet. :(
I would contact the author of the site directly. He is one of the
managers of this group, but I'm not sure if he actively reads anymore.
While that is the original url of the 1.0 spec, google groups had
become the home of the specs, up until recently. Google groups shut
down the pages option, which is a real shame. I have the spec living
up on a different domain, in a less that pretty format, at
jsonrpc.org. Others from this group do have the spec hosted on their
sites as well, or even on github.
