Thank you so much for this plugin, which I found very handy. The new Edit Media page in WordPress now includes an Author drop-down list, which means this functionality has finally made it into the WordPress core. Moreover, if this plugin is active, it actually prevents the new core functionality from working. I just discovered that the hard way.
Is it time to retire this plugin? We can take up a collection to buy it a gold watch. :)
Thanks again for all your hard work!
