There is no question that a user should be able to sign into a website account using any of the emails associated with their account, AND the username they have created for the site. For interaction on the site, it is better to identify the user by their username (as opposed to email)... but when it comes to signing in, either should work.
I also now recommend, in addition to OpenID which has been mentioned here a couple of times, considering using Facebook Connect. It is not only an easy and convenient way to sign in, but it also allows the user to broadcast interaction on your site, back to their facebook newsfeed.... now you are getting free advertising to that users relevant social group. Secondly, integrating Facebook Connect also allows you to see that users Facebook profile information, and the information of their friends... you can only store it for a day (I think), but you can create experiences that are highly tailored to the individual user because you know so much about them. I strongly advise looking into it... it is one of the most powerful advances in SSID and the social graph that we have seen to date. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
