I am integrating facebook connect into my signup area of my site, I have a regualr signup which saves a user email and password in DB for signup and now there will be option to signup and login with facebook connect. I was planning on just adding the email hash that facebook sends to my login table for that user and in there roadmap, this month they sey they aregoing to be giving back the users real email address, anyways there is a flaw, what is facebook user changes there login on facebook then my email I have for them would be outdated, does facebook send updates to me like this?
