Spot bulletin (6)
I believe the answer is:
notice
I believe this clue is a double definition.
'spot' is the first definition.
(I've seen this before)
'bulletin' is the second definition.
(I've seen this before)
(Other definitions for notice that I've seen before include "See; advert" , "Observe - written announcement" , "'Observe, discern (6)'" , "Don't miss - review" , "Detect" .)
