It has come to my attention that there are many websites with vague and weird names that try to impersonate this website. They offer the same documents as I do, but try to trick you into a (recurring) payment scheme and if you go ahead with this, you end up with nothing and a few dollars less in your wallet. The worst case scenario is that they walk away with your credit card data.
Please be careful out there and download only from this website. I think I've proofed over the years that I am not after your money and that you can safely download all your documentation. For free.
