Hi David, I already experienced this new "beta" format a few weeks ago when one of the CA Lists changed over. And, I don't really like it ! But, I only have time for one comment this morning ! One of the complaints for the new Mailman format is that it is no longer "clear" --- how we "respond to List." Do we still have the choice? Respond to sender vs. respond to List ?
