CMS for blogs, wikis, forums...?

I’ve been looking for a good (in terms of usability, features, looks) CMS that would help create and manage blogs, forums and wikis (in addition to creating and managing web pages, news, etc.). Although in the "CMS" space MODx seems to be very good when compared to others, I see that it cannot do forums (requires SMF or other software) or wikis (requires MediaWiki or other software).

Questions:
1. Is there any free (and preferably open source) CMS out there that provides blogging, wikis and forums (either out of the box or through easy integration with its own extensions - not external applications that require a completely separate installation and administration)?
2. Are there any thoughts on the MODx roadmap to provide extensions or features in the core to support wikis and forums without resorting to something like SMF or MediaWiki?

Note: I’m not actually someone who can code these for MODx. So please don’t ask me to go develop these things myself.

Thanks for your time!

I really recommend to get a proper forum (SMF, phpBB3 etc.) and intergrate it, rather than using a CMS-included version. Latter are usually very limited in options and features.

’Good’ and ’CMS-included’ are paradox in this case, same applies to wikis.

So, is the choice either something complex like Drupal or MODx with third party forums/wiki integration (like SMF/MediaWiki)?

What about the MODx roadmap? Is there any plan to develop different kinds of user interaction and collaboration features (again, I’m looking only at my needs for forums and wikis first)? I understand there are already better solutions out there, so even extensions to MODx that accomplish the same would suffice.

On a related note, can MODx be integrated with SMF and MediaWiki (or any other wiki) and provide the end user with a single sign on (SSO) that can be used across the three (like say, logging in once to comment on a blog created in MODx, then posting in SMF forums, and then creating/editing entries in a wiki without having to login individually)? Is it right to assume that at the very least, an OpenID based solution can be made to work with all three? If yes, any pointers on the same?

Thanks!

There is already an intergration of SMF in MODx.

There are CMS with native wikis and forums, but those don’t even come remotely close to the quality and features of a separately developed boards. And you need to keep in mind that your users will most likely have seen ’real’ forum boards and wonder why yours is lacking the usual features, if you use a native one.

Thanks. I understand your point of view, but I was looking for something that would reduce administrative overhead (in terms of end user administration as well as site administration like upgrades, database maintenance, etc.).

I still like what MODx promises to deliver, keeping things as simple as possible. I have a different question though that I’ll post as a new topic instead of polluting this one.

If anyone has more thoughts on this topic, please do chime in.
