I am designing the account system for a site and I need to decide how best to handle connection to Facebook vs. natively registered accounts.
Some options I have considered:
Make user sign up with their email, then give the option to expedite future logins with Facebook connect.
Let user have the choice between email signup and Facebook connect,
and if they sign up with FBC, then give them the option to associate an email with the account.
I know there's something obvious I'm missing but I don't know what.
