The short answer is: you. This website is moderated by the users. Karma system allows users to earn rights to perform a variety of moderation tasks
The picture that appears on the users profiles is called gravatar (which means globally recognized avatar).
Here is how it works: a cryptographic key (unbreakable code) is calculated from your email address. You upload your picture (or your favorite alter ego image) on the website gravatar.com from where we later retreive your image using the key.
This way all the websites you trust can show your image next to your posts and your email address remains private.
Please personalize your account with an image - just register at gravatar.com (just please be sure to use the same email address that you used to register with us). Default image that looks like a kitchen tile is generated automatically.
No, you don't have to. You can login through any service that supports OpenID, e.g. Google, Yahoo, AOL, etc." "Login now!" »
Goal of this site is to collect the best quality exercises and puzzles. Allowing other users to edit, allows us to improve the quality/clarity of the exercises/puzzles.
