Ok a lot further advanced than I had envisaged. I had seen it for vintage computers and components but since posting the website and seen a few replies about the individual cataloging what they had, it seemed the initial catalog work was the p.i.t.a. My intention was to post pages of who had what with a search facility, and let them contact each other. It was getting rid of some household bits that gave me the idea and its possible this would be better served by a listing in Freecycle. My problem with that is that Freecycle seems to be a fast turnover system with "I have this" or "I want that". In the vintage computer / component area I though this challenge response system might be too restrictive (possibly). Although some work to set up initially, I thought a central repository of parts where you could search for bits when needed and then email the owner might work better. Those individual "Fred" & "Mike" pages could be set up for Fred to upload his own data as a text file used to generate the "Fred" page with a bit of coding, that way each member of the system could change it as and when they had time. More comments / suggestions ?.
