I don't know if anyone uses the Today's Messages
link at the top of the Message Board (Forum) Homepage
, but if they do they may be missing half of the new posts. This is due to the fact that it doesn't list all the new posts made in the last 24 hours, but only those made after midnight local time in England.
If you were to live on the western half of the USA and did your posting in the evening, you would see very few new posts had made it to the Today's Messages list, while a great many had been added to the Board in the last 24 hours.
