Website maintenance volunteers?

[Jeremy C. Reed]

Another option is ikiwiki which I have lots of experience over the past 
year with.

The content is not stored in any database. And you can use your own 
backend such as GIT or Subversion and others.

Then contributors can choose to maintain the website using the revision 
control system instead of (or in addition to) the web interface itself.

The default content is stored in Markdown format. It is pretty trivial to 
convert the data to different formats. I use it to convert to LaTeX and 
then to PDF in a nice book format.
