I am new with drupal, and I want to use it for a website. But parts of the site should be in form of a WIKI, and I am not quite sure if drupal is a good idea for it.

I have seen in other postings that there is some kind of WIKI support, as with the module for mediawiki. But how does the integration between drupal and WIKI work. Is it possible to fully integrate it in the site und to use the same users, search possibilites, etc.

As well I was thinking about using version 7 that seems to have quite better support for semantic web features. But the module is only available for v6 right now?

Does anyone has any experience with wiki inside of drupal??

Thanks alot!!
