    Dear Seaborg users,
    
    Several changes to the Seaborg LodLeveler class structure will take
    place on Tuesday, January 18:
    
    - The current premium classes will be consolidated into a single class
    with a relative scheduling priority of 3 (next in line after the
    interactive and debug classes).  Its wall limit will be 24 hours.
    
    - The maximum number of nodes that can normally be requested will be
    299.  A new class (reg_300) will be created to accommodate requests for
    300 or more nodes.  This class will usually have a run limit of zero and
    special arrangements will have to be made to run jobs of this size.  The
    consultants will contact users who submit jobs to this class.
    
    - The reg_128 class is no longer being used and will be retired.  It
    will be replaced by a new class, reg_256.  At some time in the future
    jobs submitted to this class will receive some scheduling assistance.
    This is still being worked on, and for now reg_256 will have the same
    relative priority as reg_32 and reg_48.
