How To Delete Account

At one point I was able to consistently access this feature by hovering my mouse over the user icon in the top right-hand corner (in Safari), but it appears I am no longer able to find the delete account option. My premium membership recently expired thus I am wondering if deleting one s account is presently a premium-account only feature? If not, can someone please direct me to the correct place/page to do so? Thanks in advance, Ninja
