Thanks for such a quick response. It is helpful to know that the Next Actions List is the intended venue for due dates. GTD seems to recommend that the a person be reminded to take action when in an appropriate context. What is the appropriate mechanism that would remind someone that a due date on the next actions list is imminent?

I am using Outlook 2010 and Blackberry. I'm currently digesting the GTD best practices guides for these tools but would appreciate any hints related to the tools and my question.
