What is the “best” free CMS for my needs? [closed]

Question

I have the task to build a web-site for a smaller non-profit organization. I have a bit experience with ASP.NET but because ASP.NET hosting is rather expensive here in germany (we will also need a lot of webspace and traffic) and aslo because there are quite a hughe list of features I think I should go with a PHP/MySQL based CMS (correct me if I am wrong). The question is wich one? There are are so many free CMSs out there. If I tell you what I need, can you tell me what would be a good choice?

Here are my requirement (sorted by priority):

1. Ease of use (installation, configuration, maintainance) for me who builds the site but also for the members of the organisation they must be able to easily change the the content of some main pages, add supages, add a new mailinglist upload a file to the repository etc.
2. A membership/role management system. Based on the role of a member access to certain subpages, subforums or folders in the file management system etc. must be restricted. Only certain roles must be allowed to add new mailinglists or moderate the forum.
3. A mailingsystem that allows me or the members of the organistation to add new adresses, maillinglists or newsletters.
4. A file management system. Members should be able to upload arbitary files on the server and browse them via a web frontent. Access to folder should be restrictable based on the member rights.
5. A pulbic forum with private subforums.
6. Localization. As much as possible of the final site (if not everything) that is presented to the visitor of the site as well as to the members who maintain the site should be presented in german.
7. Good control over design/look and feel of the overall site. I should have good control over how I want the site to look like.
8. A lively community with enough momentum to find ressources and help when I am lost.
9. Extensibility. In case there are some smaller features missing or f the behavior of an existing feature is not quite the way I want it, it would be cool to easily add it myself.

Answer 1

As a complete CMS noob, I asked myself the same question. I started with Drupal. Sure you can do lots of things with it. Very extensible and customizable.

But after implementing my first site in Drupal, I decided to create the next one in Joomla, to have a frame of comparison. Conclusion: Joomla is a looooooooooooot easier to get started and takes a lot less time to create a functioning website from scratch. Sure, for very big projects, Drupal lets you customize more, but for the type of project you suggest: I would recommend Joomla...

Answer 2

Concrete5 is a new Content management system that is excellent. Easily themable, user friendly, great little dashboard for management

and it's open source

Answer 3

I would go with Joomla too, even though I'm a ASP.NET developer. Joomla is very flexible and customizable, so it fills all your need, because of the big community.

Answer 4

Joomla! would seem to fit your needs, and I'd also suggest Kunena for the forum (which integrates with Joomla) and DOCman for the file management solution.

Answer 5

I'd vote for DotNetNuke, it's ASP.Net but that saves you the overhead of learning a complete new environment, language and tool just to implement a 'free' CMS, realistically how much is your time worth? It meets all your criteria, and there are currently 600,000 users - which means that you can just get on with it, somewhere someone has already worked on your problems for you.

As for expensive hosting, why not host in another country, I get US$5/month for DotNetNuke in the states, and I code from Australia.
