Briefly looking over this site I would like to suggest that another category be set up. This being "UNANSWERED QUESTIONS". The ones out there over; for arguement sake; three weeks or more are highly unlikely to get a response. Though if they were all in one place and highlighted as unanswered people may actually go and look through them. Try and get local companies/pubs etc. to sponsor if need be. Once answered these items would be placed under their appropiate index/etc.
kind regards
