Hi Liz,
Great question! To create a view click on the current view and New or Save View As. See link: http://screencast.com/t/G4OudF7qeo0e.
1) View that includes only tasks due this week, navigate to a Due Date column and filter by: This week > Save. See link: http://screencast.com/t/k9DUc3WaWIIj.
2) View with tasks that are overdue, add a column Status and filter by: At Risk > Save.
For further clarification, please hop on one of our daily Q&A webinars (see the link-> http://www.clarizen.com/live-demo-europe.html ) and ask for a demo. These are great resources for free consulting with our Customer Success Managers and visual answers to your questions.
All the best,
Diana
