We would like to start a wiki about Berlin and its history. For the moment we would like to be master of our content, that is we would like anyone to be able to read it, but only members of our group to be enabled to write/edit pages. Is it possible to achieve it with MediaWiki? Is that a possible Preference? Daoes it depend on MediaWiki or on the wiki farm?
Will it be possible to change the name of our wiki in the future?
