Maplestory "High Five" Private Showcase

Can anyone explain to me how to get points for the "spread the word" or whatever event? I heard of some people gettin 800 points in a day when I am stuck at 400 from yesterday and cannot share again today.

If you scroll to the bottom of the main V micro-site page, you'll see 15 squares, of which 4 have stuff in them.
Each square, when you click on it, takes you to a page that has its own "Share for points" button.
Sharing the four revealed squares' pages, plus the main page, gives 1000 points (200 per page: 100 for fb and 100 for twitter).
