First of all the increase in volume is temporary due to the contest that Zero is involved in right now; I'm certain it will drop back to very low volume afterwards. We didn't have a single message for several months before this contest began! The point of the list is for Jane to be able to alert readers when there's something new or interesting. The DABWAHA contest has sort of shanghaied things temporarily.
Second, you can change your subscription to daily digest, meaning you'll get a single email with the day's messages in it, or you can go to No Mail which means you won't get any messages and will need to go to the list's website to see any incoming mail.
