- You can submit only one answer. If you submit multiple times, only your last answer will be taken into account.

- You need a score of 1 or higher to appear in the scoreboard.

- When you are not yet on the scoreboard and if you are submitting an answer, make sure that the name you are using is not already taken by somebody else.

- You may ask anyone to help you, but only one person will get the point if the answer is correct.

- Your email is only required if you want your gravatar displayed next to your name on the scoreboard. Your email will not be used for any other purpose.

- If your name appears on the scoreboard, you may submit future answers without specifying your email again; just your name will be enough.

- Whether your name is in uppercase or lowercase, I consider this as the same person.

- If you want to change your scoreboard email, you can send me a message (do it with the current scoreboard email address, so that I can verify your identity).

- If you have any questions, feel free to contact me.
