I suggest adding a wiki like facility. so we can add sections like

Tips and tricks
- Exporting to Youtube (other video server)
- Guide on Making awesome DVD's
- Work flows, optimizing you environment
- good practices

Cameras, film and other Footage
- Redone camera how to use it in your work flow
- xdcams
- dvcams
- phantom

just some ideas that jump to mind...

We already got it:
