Wiki-like "create this page" with page manager? I want to make it easier for editors to create new pages with page manager.  Is there a way to provide a "create this page" functionality for non-existent paths, so that editors can insert a new path in existing pages and proceed to create and edit the new page, just like editing a wiki?

I am wondering if I can implement this feature by using a menu tab like this to redirect unhandled path to the page manager's creating page.  Helps are very much appreciated.
You should achieve that by using the following extensions:


wikitools
freelinking


You should have a look at this screencast:

It is done with Drupal 7, however, wikitools is still in alpha for Drupal 7.
