Within each location, each user needs their own mapset directory,
which must be owned by that user. Users will be able to read maps in
any mapset, but can only create maps in their own mapset.

You can either:

a) pre-create the mapset directories; as well as creating the
directory, you need to add a WIND file, which can be copied from the
PERMANENT mapset, or

b) make the location directory group writable, and let each user
create their own mapset at the startup screen (however, the tcltkgrass
interface currently doesn't allow this; you have to use the text
interface to create a new mapset).
