when a user subscribes, i set the option to send them an email to confirm
when they click the link, they are shown a page that is rather confusing
no where is it made clear that their confirmation was successful and, instead, it seems like further action is required as they are shown options to manage existing subscriptions
with the default 2013 theme, there's that big orange "Update subscriptions" button at the bottom which i think is deceptively easy to click. the problem is that "Suspend" is checked by default, so they could easily end up unsubscribing to the content they just subscribed to
my suggestion is simple: there should be 2 h1 headings, the 1st being "Subscription confirmed!", below which is listed the single item they subscribed to
the second heading should be the "Manage subscriptions"
