He was complaining about the spam or ad or porn emails sent to this
group which tends to cut down traffic. It's nice you don't plan on
shutting it down but would also be nice to set some restrictions like
moderating the first message from every user or approving memberships.
By now you would have to delete the spammers from the group also...
it's a job but worth it. Those spam emails spoil the whole thing...
just a thought...
