Even with only two of us able to add new images or change status (e.g. unsearchable to searchable), there are plenty of times when we end up with duplicates in the DB. If all the moderators and item hunters could do it we'd have havoc -- 4 of some things and none of others.

But the best argument for not doing something like you suggest is that Webbie has set up the site just the way she wants it. While the prices from ImproveNeo have been a great little bonus, they really aren't what this site was designed to do.
