Just a thought: When NW was closely aligned to CO, they had the same kind of UG sweeps jointly for WP and OP members. Presumably, that means that they, too were running SHARES? And, presumably, when merging with DL they switched from SHARES to a system that is not powered by steam? If this assumption is correct, then WP members will have gone through the opposite transformation that MP members are now about to experience. If that is the case, it would be interesting to hear from any WP survivors what their experience was, good or bad, as far as the reservations system was concerned - as opposed to the well known (but, I believe, now overcome at least in part) unhappiness with a number of other aspects of the merger.
