I need to create an acct for the forum (here), another email sub for "Enter email for updates" (top right of your main page, which uses an RSS icon, though it's just an e-mailing list), and yet another email opt-in just for the "Ten Thinkers" bonus audio file.
Three different sign-up's, and two on your front page that appear to be simple e-mailing lists, but are completely separate from each other.
