The AddThis WordPress Plugin now allows you to easily track Address Bar sharing. When activated, we now allow you to track and see how people are sharing your site when they copy the URL and paste it in an e-mail, instant message or anywhere else. To activate it, upgrade to the latest version of the plugin and check out the Advanced Tab.
We also have tested the plugin with the WordPress 3.2 Release Candidate and everything looks good.
If you notice any problems, make sure to head on over to the AddThis forum.
