I'm looking to implement a company wide wiki site where the entire company can contribute too.
I've been looking at MediaWiki mainly because it is the most popular. What I do require however, is some type of ACL (access control list) so that I can keep IT's documentation separate so that the general users can't read up on our network infrastructure.
Would the best way to do this just be 2 databases and 2 separate installations?
Edit (additional info): The wiki is mainly for documentation to get rid of the thousands of Word documents on our file server that aren't searchable nor easy to find.
There will be a wide range of documentation such as safety, IT network and admin docs, branch specific documentation, et cetera.
It is possible we may implement department specific documentation where the ACL would come into play so that for example, accounting couldn't access operations or IT documentation.
