Does anyone not have the Allowed Sites feature yet? I see to not have it in my adsense setup. Do you have to configure Adsense someway?
In the adsense menu click on Adsense Setup and right under that you'll see Products | Color Palettes | Channels | Competitive Ad Filter | Site Authentication | Allowed Sites Click on allowed sites
They put it back again for some people (me at least). Looks like they are just testing right now... Just wait a while and check again, eventually it will show up.
Did you add any sites to the list before they took it off your account? If so are they still there when they added it back?
Yes, I had some sites on before, and they were still there. The option wasn't activated though, so I had to re-enable it.
Yes, I see that option on my account. I think is a useful feature, and I'm going to use it now. EDIT: Mmmm, I see: "If you put your ad code on a page not on this list, ads will still show, but impressions and clicks will not be recorded.". I hope that this feature has been well purified.
