Sorry @Fosters - did I send you this information? Can't remember if I did and deleted it or if I forgot.
BTW, another thing I noticed: when I set a notice's expiry date range, e.g., from December 7 to January 15, when I save the settings the end date is always increased by one. That is, when I save the end date as January 15, when I re-view the settings the end date is always January 16, or always one day more than whatever I set the end date to. In fact, the end date increases by 1 every time you click Save or Save and Reload!
Please let me know if you want admin login info to check out this or the issue with dismissing notices.
