[affs-project] wiki?

[graham]

Hi,
How hard would it be to add a wiki to the affs site and make it
writeable by members? One of the advantages of real-world membership of
an organisation is that we already know who should be allowed to write
to such a thing... 
AFAIK the wikis currently run on the machine are all personal, so it
would be better to start a new one from scratch.
Reason: could encourage people to contribute to the affs site, which is
hard to do now. 'Finished' pages could be moved to the public site.
Cheers
Graham
