Daily Puzzle Submissions! *Be Involved*

I already put this as a forum topic (http://www.chess.com/forum/view/more-puzzles/unrealistic-puzzle-mate-in-7), but I decided to also post it in here. Mate in 7. Difficulty: Medium.
h8=Q# also works

I'm afraid I made the obvious mistake. That's a really nice and unexpected defensive resource White has!

Yo A-232 nice puzzle, working through the endgame is always one of the best things a player can do. Again nice puzzle.

Please post puzzles that are hard, looks like one, and IS A PUZZLE.
Well...the puzzle I posted on page 35 sure is challenging...knock yourself out.

I was talking about SOMEONE, not you. Anyway, you're right. It is challenging, which leaves me with one question:
Why are our daily puzzle submissions not posted?

Hello Chess.com members! Would you like to be involved in the "Daily Puzzle"?
..Mate in minimum number of moves..
this puzzle is difficult because the black King magically can move (jump) to "any" free square unattacked by white pieces..
..some solutions are less than 16 moves, can you beat that?
Simply Ra7 and Rh8 mate.
