How do I change the name of an area I have created for a project?
What you'll want to do is go into Project Areas from the Project Dashboard and hover over the Area you want to change. A Delete link will show- delete that area. Then click the 'Add New Area' link towards the top and make the new Area name you'd like.
Note: this will not go backwards and change the Area on any Items themselves (because you wouldn't want to lose any 'before' images for those Areas, as they are linked by name), just going forward as a choice for new Items.
