Good idea bones.
I think that whoever makes the videos doesn't have to be on a tut staff, cause I doubt we will have a tut staff. I really don't think we have that much to manage. Huge forums that have lots to manage usually have staff divisions. Anyway, I think that, at least for now, people should make the video tutorials on their own time. For example, if you feel like making a tutorial but lack inspiration, convert a text tutorial to a video, upload it to YouTube or Vimeo or whatever, and send it to Gimper to be added to a tutorial page on Gimp-Tutorials.net.
If that would be successful enough, I think a huge YouTube account would be good.
That's my humble opinion.
