I used this in 1999 or so when I had just started out using linux. It was a huge pain to get running. It was for US citizens only or something, and I had to have my parents write to the government requesting the decryption key for the installer. It may have required something crazy like a fax.

After I got it running I had some trouble getting it to do things and wrote to the email address asking for example files. Mike Muuss himself wrote back with a bunch of demo files attached.
