Yes, I think that must have been the clue they meant :) Only 1 vid-only sign up + only 1 vid this round (and a BBC one at that, which neither Sang nor I -- the other 2 vidders who commonly hang out at this exchange -- offered) does lead to a pretty incontrovertible conclusion :)

For the same reason, I'm sure the BRILLIANT Buckingham Palace treat is from Dee_Laundry, too. It was originally intended for only Write_Out, their assigned recipient, but they expanded it to Saki101, too, in thanks for the lovely & generous comments of them both. A lovely idea!
