This is pretty ugly but it does what you want I think:

[stuff]
	comment = Shared stuff
	path = /home/stuff
	force group = users
	read only = No
	create mask = 0660
	force create mode = 0660
	security mask = 0770
	directory mask = 0770
	force directory mode = 0770
	directory security mask = 0770

Add the users you want.

HTH Steve.
