I just tested search a little bit--it's not clear from the box at the top that you are only searching the forums. Also, in the forums, sometimes messages are not appearing in date order--see my imported message at
http://208.184.248.90/forums/message-view?message_id=33419 . The messages are out of order.
Lastly, is there no way in the search results to show the date the message was posted?
