Rename "Projects" to "Workspaces"
I think there is some confusion on the term "Project". Even the way the tutorials and webinars describe how Teambox/Redbooth uses it's own product seems to make each "Project" more of a departmental workspace that has several projects going on inside of it. The actual projects seem to be inside Task Lists. With this in mind I think renaming "Projects' to "Workspaces" would let people use them in either capacity as either a general space to collaborate or as a project specific place. Either way the language is less confusing for newcomers.
Ability to rename Projects should be open to choice/needs of the user. Clients, Stores, Cars, Teams, Patients...
