Currently, you only see the name of the license(s) when you browse an item. However, if the person downloading the file doesn't know jack about licenses... It would be good to link to them I think. Or link to a page which teaches a bit about free licenses (maybe links to freedomdefined.org) and then to the individual licenses? Also, it would be *very* useful if OGA automatically created and provided for download: text files that contain a copyright note (see below, only if it's not cc0/pd) and the full license text (or at least a summary plus link to full text) of the license.

Just one question, why let unregistered people/guests access the upload form, if they would need to register & login first anyway's? Just prompt them to register first. I mean, it is rather confusing, I actually uploaded a model twice in a row be caused of this. Sure easily fixed if you pay a little attention and see if theres a way to delete the file, but even so the delete button is rather well hidden(though it should). Just a thought. ;)

I just created http://opengameart.org/content/door-open-door-close and got following error message: warning: filesize() [function.filesize]: stat failed for sites/default/files/door.7z.preview.mp3 in /var/www/sites/opengameart/sites/all/modules/rules/rules/modules/php.rules.inc(100) : eval()'d code on line 21.
