How hard would it be to set up a database of people who have various bits of hardware?
A database On GDNet could only give email addresses out to members and keep a log of who got what (to prevent abuse)
A timeout on entries is also probably a good idea, because some people tend to change hardware quite a bit. Let people chose how long they want to stay in the database.
Also give the option of emailing people when they drop off the database sending them a url of a form if they want to update their data and stay on the database.
I know it's a bit of an ask, but it would be quite a usefull scheme, priceless to someone who needs to find a system with a 16 bit BGR display with an Awe 64, just to fix a bug.
