I really think you should remove the new lab submissions from the tut/articles list on the main page of your site, or at least type something in the title that suggests it’s a lab submission.
Just so members don’t see it and think “OH, a tut on the matrix effect!!”, and then get all dissapointed when it’s just an fla they can download and don’tt understand jack of =)
IMO… and the fractal tree also…
