17:30 Planning the Chiefs Meeting for February, 2001 (splinter meeting)
Ed Himwich
 Purpose: The Chiefs Meeting is one of the primary training forums for geodetic VLBI operations. This splinter meeting is intended to help develop a consensus about the format, and possibly the date, of the next Chiefs Meeting. A significant issue to be discussed is whether we should continue the historical style of large infrequent meetings, move to smaller more focused and more frequent meetings, or some combinations of these. Another important topic will be collaborating with other groups, such as the EVN, on the organization of these meetings.
