We've seriously considered this idea! Let's just say there's a very good chance of something like that happening soon.
We've seriously thought about it...but the BioTube fandom didn't exactly have the biggest plethora of videos on a weekly basis that we wanted to showcase. Also, we'd be a little pissed ourselves if someone basically rehosted our video while just adding a bit of a commentary track. Maybe if we find a way to better balance it and when there's a regular stream of great community videos when Bionicle's back, we'll dust off this idea and try it again.
