Inside of the Forum they will find an area called Email Settings. Click on the Change your settings link and from the pop-up check the box next to "Email me about new posts in this group and send me those emails..." then select the way in which they want to receive forum posts. They can have each post sent to them individually (individually as new posts are made) or they can receive an email digest of the posts (as part of a Daily/Weekly/Monthly email digest). Once a user has set up these terms, then they will start receiving digests based on their settings.
