CRM and Project Management for Small Business
Wrike is very fast, has excellent Gantt charts, tasks can belong to more than one project, has a 3-pane display, email integration, and collaborative editing of task descriptions using EtherPad
Good design
Great for Basic Project Management and Collaboration
We have been using this for a few months now, with about 30 users. It works really well!
