There is a new mailing list feature.
You can now choose between a full distribution or only replies to your messages. The full distribution was there before. What is new is the replies to your messages. This is really useful when waiting for an urgent response and don't want to stay on the Web to wait for it. You are now able to get it in your email. As the mailing list was before, you can then reply to this email via email as well.
Available for PUTM only.
