• The verification link doesn't have an expiration date, so whether you click on it a minute after it has been sent or a week after, it makes no difference
• The verification link can only be clicked once. From then on it is disabled.

Once you have clicked on the verification link, you should be redirected to the Layar login page.

If you don't remember whether you have clicked the verification link to activate your account, or you have clicked on it but have doubts as to whether it worked, just try logging in on Layar.
