Stuff like DIY Tutorials like
The Zune in Book Tutorialz
how to make a mini sub for your zune like Robb has, and people have made duct tape cases, and my super famous NES speakers
Also there could be a DIY questions section.
Me and Saline like to make stuff and would do so more often if we had a section where people could post ideas and links to tutorials.
I figure if we have a tutorial section that is mainly for software why not have one for physical objects.
