my site has 4 oauth login providers but i am missing the page that asks users to enter their email so that user accounts are not duplicated. for example, right now if a user logs into site w/ fb oauth, then comes back and logs in with twitter, the accounts are different. Requesting user email ties all oauth logins together to prevent replication.
please explain what i am looking for so i know you understand the problem and how to solve.
need this done tonight.
