Is there a way to get email notifications for new discussions in the groups I subscribe to? I only get notifications if there's a new comment on the group itself.

Failing that, is there a simple way to send out notifications for new discussions (perhaps manually) to members of a group? Would that be considered spamming?

I just want to keep tabs on my groups and allow others to keep tabs on my group, without having to continually open the various groups to look for recent activity.
