Hi Ken, The article that Doug linked to should provide sufficient information on how the system works. As for the original intent, we believe that a project has 4 main statuses that they typically go through: Planning / Execution / On Hold / Complete. Planning would also include Requested or Idea, and do not send out most emails, as it's expected to undergo many revisions during this phase, including assigning resources, realizing they may not be the best fit, and thus removing and reassigning different resources. The Execution phase would entail a status of Current or equivalent, and would be where work is actually done on the project. This status/phase would be where we would send out emails, such as when a task is complete, a predecessor is completed, assignments are changed, and the like. On Hold is just as it sounds, in that there is something holding up the project. Complete as well, is just as it sounds.This would encompass Complete, Closed, Resolved, Cancelled, Dead, etc. This is when an actual completion date is typically set, and no further work is done on the project. Statuses can always be changed later down the road, with the only setting necessary to check is the completion mode. If it's set to automatic, you won't be able to re-open a completed project. If it's set to manual, you can re-open the project as needed. I hope this helps! Thank you, Dustin Martin Assigned Support Engineer Workfront
