The direction that novell has taken is that we need to make our lives as
Groupwise admins easier and the best way to do that and a way to save
money is to consolidate and reduce the number of PO and Domains we are
using. THey used to tell us that that had many size limitations and we
should say small but this is no longer true. This coudl easily be done
in about 8 PO which woudl make your life much simpler.

Hello Steven
I think the concern was the time taken during maintenance and segmenting
off
users into their own PO to limit the impact to other users when things
go
pair shaped.
