You may have noticed ads are now appearing on the site. Nobody likes seeing ads, but we've been talking with our owners and ads are what will enable us to keep this site and its servers running for free.
The location and nature of the ads may change as we adjust them, and as Google tweaks its algorithms for our site.
Each ad has a ► button where Google will try to explain why the ad is showing what it does, and a × to tell them why you don't want to see an ad - including to report it as inappropriate.
