Now that you're an expert, you should be able to do it yourself. You see the column where Oswald's puzzle points are listed? Under that, there's a button for 'add' and a button for 'subtract'. Just hit 'add' once, and you've awarded him a point.
Then you go to the bottom of the page and press 'Move topic'. Then you:
a) select "Move to: Puzzles, Games and Name That Car - Solved AutoPuzzles"
b) DE-select the "Post a redirection topic" button
c) select the "Change the topic's subject" button, and call your post something in the direction of "Solved: Djetset #12 - Nota Formula Junior". That way, it is easier to find the puzzle later when searching.
Good luck.
