Only to find Special:Export and its tiny ticket window of data export "yes Sir, which page would you like to export?" "What, you want more than one page well you'll have to list them one by one. No, you can't just 'have them all'".
you can add categories to grab groups of pages. Offering a daily dump is easy enough for my wiki, and I rather generate that daily with a "nice" process rather than someone clicking "export all" and the site going down because everyone is running 10 minute+ queries
It is easy enough to make a link from the export page to a full "xml" dump too.
Best Regards
