What happens when Rob is ill or on vacation? Does the group meet without him and does that meeting count toward the four-week series?
No. Only meetings with Rob Kaufman count toward your four-week series. When Rob goes on vacation or is unable to attend a meeting for personal reasons that meeting does not count toward your four-week series. Usually the group does not meet when Rob is not available, but sometimes the group may decide to meet on their own, without Rob, maybe over dinner, for example, but that meeting does not count toward your four-week series.
