Wow, this is a cool idea. Makes me want to sell CDs again now that I can avoid eBay (I'd call it eGay, but it's insulting to homosexuals to compare them to eBay...).
Can we list guitars 'n gear too? What about selling ourselves... like if any attractive metal women need backrubs?
I will be adding an equipment section (guitars, bass, amps, etc.) in the next few days, hang for that. Any other suggestions on different categories anyone?
