I would like the counter to count only unique hits. I don't want the counter to go up each thim the same person goes back to the home page or refreshes a page.

This feature is called Session Tracking, and it's available for Premium accounts. If you already have an account and wish to upgrade to Premium, you'll find an upgrade link on the Options menu of your main stats page. In order to enable or disable this feature, Premium account holders can login to the WunderCounter and choose "account options" from the "options" menu. Just follow the link near the top of the page which tells you whether the feature is currently turned on or off and you will have the option of changing this setting.

This setting begins to work immediately, but it is not retroactive. That is, it will not remove hits earlier on in the day that were *not* unique.
