Add the WikEd editor into QualityBox. You can add it via MediaWiki:Common.js so that would have to be distributed. Otherwise, you can add it as a gadget - but again, that would have to be distributed. wikEd is installed on the demo site right now. So, the real issue is to determine the preferred method for distributing content with QB.
We can easily make a default database, but what about versioning content as external files to be loaded? That would give better visibility to what’s distributed, and even make it ‘optional’ rather than an undo step for people who don’t want the added content or features.
