Visitors Tracking

It is stated in my email update...'To view comprehensive statistics for all of your artwork, simply login to your account and click on the "Visitors" tab.' I went into my account and clicked every button I could see and nothing takes me to the wording VISITORS. So I think its not so simple for me. I went through the Frequently Asked Questions and it seems no one has asked this question. I am a premium paid up member as well. Can some one be helpful and step by step, explain where this tab seems to elude me? Thank you...
