Itinerary planning support program, itinerary planning support method and itinerary planning support device

摘要

A server receives registration of an itinerary plan including one or a plurality of spot information items. The server sets a reference status of the itinerary plan such that one or a plurality of registered members refer to the itinerary plan. The server detects that edit processing corresponding to any one of the one or plurality of members is executed with respect to the itinerary plan, in a state where a program of displaying messages exchanged with or among the one or plurality of registered members in a chronological order, is not executed. Thus, the server displays messages of notifying occurrence of edit processing or contents of the edit processing in a chronological order, in addition to the messages exchanged with or among the one or plurality of members, at the time of displaying the messages in a chronological order by executing the program.
