good idea. rather than starting another discussion- quick question: is there a way to set a resources number of hours by week? Is it under: Resource>Assign Resources>Resource Information> Resource Availability (??). And choose, by specific time frames, their availability? Reason I ask, is based on this project, certain points of the project require more time per week than others. Therefore, one week I may have someone for 20hrs, another I may have them for 30hrs, another week I may only have them for 10hrs. I think this runs into your other suggestion of leaving working times alone (at the resource level) and instead saying they are only available 50% of the time (4hrs).
