I see Tradedoubler have just updated their site. Visiting it today, there was an overlay with a link to their updated privacy policy and a statement that by continuing on the site you are agreeing to the policy. The overlay does not dissappear until you click and "Agree" button on it. This appears to set a 1 year cookie.

This would appear to cover them but I notice the blurb from Affiliate Window that visitors should have "informed choice". With the TD solution, it is possible to click the agree button without going to the privacy policy.

Anyway, the TD site is likely to be visited by the likes of us so the opt-in will not cause a problem.
We on the otherhand may need to be a bit more careful with what we present to visitors to stop them hitting the back button.
