It may seem as though the new groups being used as forums will overrun your inbox with messages but you have a couple of options here.
1. Go to Google Groups (
groups.google.com), and set your personal preferences to how often you want email.
You can set different preferences for the different groups so you get email for some but not all, or maybe one or none.
You have control of what you see and how it is processed.
