You can ask anyone's help, the only risk being that you can lure :
1/other contestants to see the answer posted
2/other people to try to win the contest.
Actually I come from this second category. A question was asked on a forum I usually post in, and I decided to take part in the contest (150$ to win) ^^
I managed to come back on everybody and am first now, for anyone who'd care about that ^^;
The trouble is that you have to get the money in their shop in a small lost town in France and I have no idea how to get there in case I'd win °_°
Voilà .
