Might I also suggest a "For Free" area in the HTG Marketplace.
I occasionally do some business in a large office building on the same floor as the IT department. I often walk by their office and see a pile of old computers, monitors, keyboards, etc which have outlived their usefulness to the business and are headed to the junk pile - however they are still in good working condition and could still serve a useful purpose.
Similarly, I would venture to guess that more than a few long-time and experienced "geeks" here may have a few bits of older equipment lying in the basement, or back of the closet, which may be too old for sale, but are still in working order and would be useful to somebody else.
The item would be listed "For Free" on a first-come, first-served basis. All shipping costs, including postage, shipping boxes, packaging materials, etc. would be assumed by the recipient of the free item - or if possible a live, local pickup could be arranged.
While of course the primary purpose of the Marketplace would to buy and sell, there might still be a place for the unsalable, yet still usable.
What do you think of that idea ?
