#	Group Administration

#=======================================================================
# TODO LIST
#  - Keep track of transactions pending completion
#  - Investigate what happens when a group is deleted, does the
#    server send a new list? obviously the upper groups get
#    a reassigned number (???). Remember that the entries in
#    the address book (::abook) contains the group IDs received
#    in the Forward List.
#	* group id is left unused until a new group is added.
