A new section has been added to the MacInsiders Marketplace called "Requests / Looking For". You can post threads here if you're looking for something, and see if other MacInsiders members have it.
If you've posted something for sale in the Marketplace, and you see a student posting a request for it in this new section, you can post a reply saying to visit your ad thread to learn more about the item you're selling that is what they are looking for.
Click here to view the new section and post a request. You can also access it by clicking "MARKETPLACE" in the top navigation.
