I have played with both.  You can allow users to do some editing, but it is not a trivial process (of course with some training it will be easy enough).  It does make a very slick content driven site though.  Joomla appears to be the more current fork of Mombo, but what works for one typically works for the other. 
I also found in my wanderings a component or module that allows Joomla to look up though LDAP so you could have your user base still sitting in NDS... er, eDirectory I mean (I haven't seen one for AD as of yet, but I haven't looked either) and not have to create accounts for all your users for every site.  That's the part that makes some of these apps less appealing to me: having to manage all the users. 
I've looked at a bunch of them, one simple one with gobs of plug-ins is Drupal (www.drupal.org).  It's not going to solve the world's problems (all we need for that is a viable electric car, some really healthy potato chips, and clam dip), but a lot of people with a mind toward education have made a lot of plug-ins/tools for it.  I even found one that links to adult sites and pulls in thumb nails automatically for you... just think of all the dough you could be making for your school... the voters would love it when you went to town meeting and told them that the school would not be asking for a penny from them... in fact the school wanted to give a little back... free accounts!
Well, maybe not... You might not want to use the plug-in, but I did see one that could make a very functional Service Request system.
You can also check into the phpnuke and it's spinoffs: phpnuke.org, postnuke.org, cpgnuke.com (Dragonfly) and another Joomla/Mombo fork called Zoomla (zoomla.org). 
I just dug up a link with a few more... http://directory.fsf.org/webauth/content/ 
Have fun,

Dear list
Has anyone out there tried using Joomla or Mambo both free and open source to develop and maintain a website. My understanding is maintenance is accomplished by allowing users to log into an editor and update. Thus distributing the burden of site maintenance.

We are interested in changing the tools we use to create, edit and
serve our web pages and would like suggestions from those of you who are
doing this effectively.

We are not seeking tools for high-powered web developers, but rather
for those teachers and students who want a relatively painless way of
creating and editing their personal web pages. This would include
teachers posting assignments, announcements, curriculum, etc. and
students publishing their work to the web.

I should mention that one of our schools has been using First Class for
these tasks and, in many ways, it has been effective.  However, we have
several reasons for wanting to discontinue its use, so we won't be
interested in suggestions involving that product.

Also, while we would be interested in hearing about outsourced
solutions, our intent for now is to try to keep it all in house.

Here then are some of our selection criteria:

..Ease of use.

..Cross-platform (Mac/PC)

..Flexible enough to employ district-wide, K through 12

..In compliance with open standards (though not necessarily open

..And, as always, "reasonably priced." (Whatever that means to you is
close enough.)

Remarks, comments, advice?
