3) log in as user2 > profile > change email address to [e-mail]
4) confirm email change 
5) view profiles for user & user2

tested with email= [e-mail]  [users= 242user & 242user1]

Hmm, I am not surprised at this, and in fact I find it a desirable feature philosophically. Is there a practical reason this is bad?

Many months ago we decided to make email addresses unique. We can revisit that decision but for right now this needs to be fixed, and can't wait on the design decision.
