For the first week or so, replies to messages received during the day will be sent out only during the evening (so that potential bugs can be identified and corrected under actual combat conditions). A (subscribe all / cancel all) option has been added that allows automatic receipt of the full text of each paper on day of receipt. This is recommended only for large groups where a single such account could be used for general distribution or posting in a preprint library.
