The old forum was hacked into and overloaded the server we used. The server owner was none too happy. Re-creating the old forum is going to be major task. As an alternative, low cost (free) and low maintenance solution there is a new Message Board page where you can leave comments. There are links above on the menu and below. Links to the latest comments are shown under the calendar.
Give it a try and see if it is going to work for us.
