I used the UWC to import from a MediaWiki instance and it's created a flat space, containing over a thousand pages, without any pagetrees. I expected the pages to be pagetree structured -- based on the way the MediaWiki articles are linked to each other. Fortunately, I can navigate the new sapce because the articles are still linked to each other.
Does anyone have any tips for fixing this? I'd like to find a spider-like tool that autobuilds pagetrees!
