The openguides.org website is now running out of the OpenGuides svn repository, so anybody with a commit bit can update it. Hopefully the structure should be easy enough to understand.
The only thing that you need to do after committing a change is to poke me, as I'll have to do an "svn up" on my webserver. This is exponentially easier than getting changes done was before ;)
Hope this is useful,
Earle.
