Ok I've not been around for a while here so apologies if this has been answered already. Around when I left this was still an issue that GTD didn't directly deal with but hey.
I need to be reminded to do something every three hours starting from 08:00 until 21:00. The only way I can find to do this in Outlook 2007 is to put it on the calendar as an appointment going against to hard/soft landscape rule of GTD. I can't see how to easily do this as a repeating task.
Does anyone know how to achieve this?
