A nice feature I've seen other places is a submission form where any type of member can fill out key fields and upload pictures and then the request gets queued until an admin-type user reviews the request. If the data is entered by someone who knows what he/she is doing, the review is easy and the admin can just accept it (and it's live in the DB). Or, if the admin has to, he can edit some of the info first and then approve, or of course, just reject it. Hopefully this feature could take some of the initial burden off the few who are entering data, doing scans, etc. It would also give all members a chance to help build the DB without having full access to accidentally mess things up.
