For my website and coming all sites from now on, i want to have a wiki system, which can -
1) Support internalization easily, that is the wiki has a system to serve contents based on the language user selects. For example keeping 'en' as default, the wiki has to be able to serve other language articles, if a different language version exists. If i have a F.A.Q. page in english and spanish, changing language would server appropriate content.
2) It should be light weight and easy to install.
3) Only i can edit contents, others has no edit option, the wiki system has to have a easy way to switch off editing by guests. All edits are admin only.
I m considering MediaWiki, but i wish to know if there is a better wiki system agreed by experienced and veterans :)
