SOLVED
Ah, Pete, your answer combined with a bit of sleep led me to the answer.
The Scheduled Rule was:
If CURRENT_TIME='09:00' AND CURRENT_DATE>=18/07/2013 Then
PowerHour
The PowerHour process:
If LoggedInSystemUser.AccessLevel='Consultant' Then
DISPLAY MESSAGE 'It is Power Hour.'
BUT THEN, I realised that in the visual perspective for the Consultant I needed to enable background processes. Seems to be running now 🙂
My goal is to surpass both you and RocketRod! One day, you will come to me for answers! (Hey, a boy can dream, right?)
