From your initial post, I gathered the Quags were off limits in any new efforts. I'm wondering about older clips. As an arbitrary example, say "Joe Blow" made a spoof of "Tribbles" 18 months ago using the Quogs. That and other Quog animations were stored upon the GoAnimate servers and visitors could play them at their leisure. Since GoAnimate no longer has that license, did G-A have to delete Joe Blow's Tribble parody video as well as any other Quog based clips?
Any Trek videos published before 9th September 2012 is still viewable. But they cannot be edited now, and news ones cannot be made using the Quog characters. I think if you know how to save the sets as templates in the goanimate studio you can still use them. But if you insert a quog character into the studio it automcatically locks your ability to publish the movie.
