I asked a question earlier about wikis and your recommendations for wikis. 
After more reading and discussion, it seems to me that a wiki may not be 
quite what we are after.

Essentially, what we need is some sort of groupware for a collaboration that
is just beginning to get off the ground.  I gather from the collaboration
that what they want is a web front-end to a central repository when they can
archive stuff like meeting notes, detector design drawings, etc., over the
lifetime of the project.   After hearing your recommendations, I tried out
mediawiki.  It's my impression that wikis are more suitable for on-going
discussions of topics.

It's been suggested to me that a CMS may be more appropriate.  So, once
again, I asked for your recommendations and advice.  A brief comparison of
the two --- wiki versus cms --- and your recommendation for a cms system.

Thanks! Ken
