> In many cases that I have come across, the DOI can be turned into a link that takes you to the article. Perhaps that would be enough.
This would be a very simple but extremely helpful change. You only need to prepend http://dx.doi.org/ in front of the DOI, and make the resulting link clickable.
You could also add the various other efforts in Open Access domain that were linked on this page to your http://thepaperbay.com/others/ page. There was at least Pirate University, articleak, and /r/scholar.
Also, while it's okay to have a somewhat complexe form to fill when making a request, it's really sad that it's as much work to share a paper, it should be very easy, in particular when clicking "I have this, send it", the form should have only one field: the file upload, or at least have the other prefilled with the request's values.
