Messages are delivered one at a time to your email inbox. This is the best option if you want to keep up on the latest posts immediately.
Messages are delivered in batches of 25 or daily, whichever comes sooner. This is the best option if you want to receive fewer mail messages and don't need up-to-the minute posts in your inbox.
This option puts email message delivery on hold, for example while you are on vacation. If message archives are available, this option also permits you to read messages at the NIMBAS Alumni Network Group Site
