You must be thinking of your dashboard and the reader pipeline. That’s available from your novel’s page, up in the top right corner. From right to left, there’s your portrait, then "update readers", then "edit project", then "dashboard". Clicking on "dashboard" should get you the list you want.
That list will also grow with all the other people you pitch to (because of course you can pitch to people not on that list) or who follow your novel. And you can also add your contacts from Facebook, email, etc. to it, though I have yet to try that for mine.
