I did send an email to Bruce explaining there were no messages entered on the IAS MB since late Friday night; but I NEVER got a reply!!
Now that the month of September is on the IAS MB, it is very obvious that people could and did post messages on Saturday, Sunday, Monday and Tuesday morning!!! I assume those people are subscribed to the Adhesions Forum - where they receive individual messages as they are posted. And I assume the were able to receive all of the messages over the weekend.
