Hi Chuck, the other discussion is still available here:
http://moi3d.com/forum/index.php?webtag=MOI&msg=1434.1

You may not see it if you are viewing only unread messages in the forum, it does this by default so it is easy to browse just messages you haven't seen before.

Switch the View: dropdown to View: All discussions if you want to see all forum messages, including those that you have seen before.
