+Members of a group have write access to their own version control
+trees and read-only access to the version control trees of other
+public groups.
Not that my opinion particularly matters, but I think it's a good
improvement. Thanks.
I suggest "write access to that group's version control ..."
(i.e., s/their own/that group's/)
Otherwise it sort of sounds like it's referring to the members' own
personal/individual version control trees, which is confusing, since
nothing like that exists :).
Best,
Karl
