People don't need to email me. How it works is that once you create an account on Kopibibli, you can create "issues". So if you have an album that is not on Kopibibli, you just have to create an issue with the name of the album. On the front page of Kopibibli, people can upvote issues. So I'm always focusing on the issues with the most upvotes. And I delete an issue once it is resolved.
I agree that if it takes off, I would need to find a better way to add content to the database. I was thinking of maybe letting people add content, but it wouldn't show up on the site until I approve it.
As for providing an API, I would definitely like to do that.
