NA Digest has moved to Cornell University, where it will be edited by David Bindel and Alex Townsend. Mails will come via the Cornell Lyris e-mail list service. The archived issues, submission form, and FAQ (including descriptions of how to subscribe and unsubscribe) are now hosted at

https://na-digest.coecis.cornell.edu/

The first issue from the new system should be sent on Friday, September 6. If you believe you should be subscribed and do not receive an issue, please check to make sure that it is not caught by your spam filters.
