We're looking at implementing Facebook Connect on our Join page, allowing new users to create an account either through a standard sign-up form or through Facebook Connect. I'm looking for thoughts on the best way to also present an email opt-in option.
On our standard form, we have a checkbox, checked by default, to opt-in to our newsletter. Adding the same checkbox beneath the Facebook Connect button seems like the most sensible way to go, but it also feels a little clunky to me.
