Get Involved!

PSNA runs an email discussion list at Any subscriber can post messages to this list. To sign up, email

If you haven't subscribed to such a list before, you might want to sign up for the digest version, which puts all the messages sent on the list each day in one message. This option cuts down on the e-mail traffic when the list is active, however you won't see messages until the end of the day.

It is important to use simple online manners. Remember your email will appear in the inboxes of hundreds of busy people, who  come to this list to have constructive conversations, exchange useful information, ask and answer important questions. You should take long or contentious discussions offline and avoid repeated or argumentative exchanges of messages, especially between just a couple of members.

Thank you for being here, and we look forward to hearing many different viewpoints on many different subject!
