Eastern Division Meeting Survey Results
The Eastern Division Executive Committee has reviewed the results of the fall 2011 survey on meeting dates. In light of these results, the Committee has decided to change the dates of future Eastern Division meetings to early January: specifically, the end of the first full week in January (counting Monday as the first day of the week). These new meeting dates will take effect in the 2015/16 academic year.
The Executive Committee thanks all those who took part in the survey.
