I don't have a decent project management tool so I have frequently resorted to using Outlook to manage the tasks. However it still is only half-decent.

I have created various categories, but I cannot create categories under categories.

I have created tasks, made tentative assignments (finally figured out how to do this!) and have put the estimated effort in the Total Work column. So far so good. Now I need to know the sum Total Work for all tasks grouped by a specific resource. Can someone help? A ready macro or code snippet would be highly appreciated.
