A list management server for adding or deleting an information provider terminal, which is monitored by a receiver terminal, in a buddy list that is used to distribute information from said information provider terminal to said receiver terminal, based on an updating request sent through a communication link from a third party terminal which is different from both said receiver terminal and an administrator terminal of an administrator of said buddy list, said server comprising:

  • a list storage unit for storing said buddy list; and

    a controller for accepting said updating request from said third party terminal and identifying information for identifying a user of said third party terminal, determining whether said user has an updating authority to update said buddy list or not, using said identifying information, and, if said controller judges that said user has an updating authority to update said buddy list, permitting said third party terminal to add or delete said information provider terminal in or from said buddy list, said controller comprising;
