Export pages
From Cardenalesbbc
You can export the text and editing history of a particular page or set of pages wrapped in some XML. In the future, this may then be imported into another wiki running MediaWiki software, although there is no support for this feature in the current version.
To export article pages, enter the titles in the text box below, one title per line, and select whether you want the current version as well as all old versions, with the page history lines, or just the current version with the info about the last edit.
In the latter case you can also use a link, e.g. Special:Export/Train for the article Train.
