I've just gotten another email request for permission to use one of my photos. Of course they have permission, but I'm struck by how much trouble people always seem to go to find an address to send to. I'm thinking that we should suggest to commoners that they post direct contact info if they're comfortable with that, at least on user page if not on every image - I think there's only been one time that a reuser found mediawiki's secret email-to-user option and contacted me that way.
