If you are particularly concerned about keeping your usage of Incorporator anonymous and your email address would disclose your identity, yet you still want to save your upcoming inputs for possible future use, Incorporator does not mind if you use a bogus email address so long as it is not someone else's email address being used without their permission.

However if you do choose to use a bogus email address Incorporator will not be able to give you access to your previous inputs if you forget the username/PIN combination you have chosen.
