Although the site was designed (with url) for last year application cycle, the urls/links should still work for this year. I have checked most of the links and they are working fine. Some of them will not lead you directly to the actual secondary itself, but to a page with important information to anyone who is going to fill out a secondary. I deemed that such information is a necessary read so that you don't mess up your application. It is better to be safe than be sorried in this process. Wouldn't you agree?
Again, if you find anything new that you believe might benefit your fellow applicants, please email me so that I might update the page as needed. I am still watching the forums here at SDN for updates, but I might miss a piece of information here and there.
Good luck!
