For the first issue of inputting wrong email, this can be solved by email
verification.
For the second concern I agree if the user's email become invalid they will
not be able to receive message to this address but they still have his
account with the site. Since email will be used as the only identification
here, I'm not very confident after changing it couple of times the user
won't mess up his memory on the latest email for login.. Anyway, it's still
a good point to give some consideration to. Thank you Anthony.
