I tried out this plugin. It asks for grouptivity publisher ID which in turn asks for your Adsense publisher ID. I registered for grouptivity with all the details (including Adsense publisher ID). I am not able to log in to grouptivity site with the given user id & password. I tried requesting new password several times. Though they are quick at sending the new password, the password never works. Further, there is no option to delete your account. Now, I am concerned about the security of my Adsense ID. Can my ID be misused by them (or for that reason by anybody who knows it)? What should I do?
