The international computing community was stunned Monday following the announcement that San Francisco-area computer user Jeffrey Schaeffer had paid the requested $10 fee for the shareware puzzle game CubeMania. 'I enjoyed the game,' Schaeffer told reporters. 'And since I am keeping it on my hard drive, it is my responsibility to pay the fee.' By paying the $10, Schaeffer will receive free technical support for CubeMania and upgrades when they become available. Schaeffer also recently wrote the NFL for express written consent before watching a videotape of last year's Super Bowl with several friends.
