If you guys don't already know, The Lose Media Wiki is a website dedicated to the research and finding of pieces of 'lost media' and they're really good at it. They've had major role in the search for that one missing Spongebob movie and have played a role in the discovery of a ton of pieces of media previously considered lost including:
The Sesame Street 'Cracks' Short
and are currently taking an active role in the search for Clock Man which has led to the discovery of other unreleased Pinwheel shorts
From things like these it seems that these guys are big enough to warrant their own article
