I would like to hold a discussion of this topic at 4 pm in the MCC 
Conference Room.  All interested parties are invited.  Some of the 
putatively available time is swing/owl and some of the day shift time 
will be reserved for setup and maintenance.  All beam studies 
participants will be expected to provide a summary for the relevant 
meetings.

Michael Tiefenback (P.D. for the next few days)
