Suggestion: 'Glam Garage'

I'm impressed with all your comments of how to bring back Glam. Along those lines, longtime reader Marc wrote me an email yesterday with a great suggestion. Here's what he said:

"To help bring your community together and kept them active together perhaps offer what I would call the Glam Garage where people could sell and trade glam CDs, shirts, DVDs, autographed material, and everything related to Glam."

I think this is a great idea! Sadly, I have no idea how to do this - does anyone have any suggestions? I guess it would be a site plugin or something? I wouldn't charge any money for people to trade/buy/whatever. It would be cool to see what sort of rarities everyone has in their personal collections.

So, would you be interested in such a site addition? I can probably nag the Glam husband to make it happen - but only if there is enough interest. Leave your suggestions/opinions below.
