For the ACT Certificates: After finishing the MC question with 70% you get the certificate as a high resolution graphic file (png). It has the FEMA & Act Logo on it and is signed by three people of the University of Memphis followed by the line "ACT Online is developed in collaboration with the University of Memphis,
Vanderbilt University, and Sparta Inc." They are looking quite decent, especially for the fact that they are free. There is also the option to get some kind of a transcript snailmailed by the University of Memphis (for $15 each). So far there are 8 of them available, a few others are under review by the FEMA. They usually even send out email notices, when a new one gets approved.
And @emmzee: I had the same problem, but I in these cases I just use a friend's post address in the US. It's probably not perfectly alright, but I guess chances are quite low that they demand their png files back
