Posting to a topic
Hope springs eternal, and all that. At the bottom of each discussion page are instructions on how to email in a post to that discussion thread. You cannot sign up and post all on your own — all submissions will be individually vetted before being posted. We’ll give that a try, and see if the spam and incivility can be kept to a dull roar.
