I've been a lurker for quite a while and found the many discussions useful over the months. Unfortunately my first posting is to let people know that
I am a recent victim of the automatic failure for not implementing the 48 hour rule (my assignment is URLyBird 1.3.3).
I did document my decision not to implement the rule in my choices.txt file.
As others have mentioned in past threads, the 48 hour rule is not a "must" requirement and thus failure to implement it is not grounds for an automatic failure. After seeing threads from a nearly a year ago discussing this same issue, it is discouraging that Sun and/or Prometric still have not informed the assessors that the 48 hour rule is not a "must" requirement.
I of course will be appealing. I am appreciative that others who have had this problem and have successfully appealed their grade posted what they did for their appeal. Such information will help me formulate my own appeal.
