I agree that you need to enter as much data as possible yourself to get your tool up and running and useable for people. What I meant by seamless is that entries are automatically added to the public database. You could perhaps filter it: look for spam, exclude 100 lb sleeping bags, or pieces of equipment with four letter words in it. You could also let people flag inappropriate entries which would then get reviewed. But what I was suggesting is your database be automatically expanded and your staff (perhaps even volunteers) just review stuff that is grey area.... I am trying to make less work for you!
