Regarding escaping brackets and ampersands - would you do this prior to storing the value in the DB? This would seem like the only way to do it, otherwise you are looking at escaping after DB queries or escaping in the client, neither of which I like.

Most relevant code file:

emailIsValid uses the helper method isEmail from the validator package to assert that the provided email is a valid email format
