 * [Invitable](https://github.com/wildland/token_authenticate_me/blob/master/lib/token_authenticate_me/concerns/models/invitable.rb)

 *tl;dr*:
 * `email` is required, can't be blank, is unique (case insensitive), and must look like an email address.
 * `password` is required, can not be blank, it must be confirmed (`password_confirmation`), and must be between 8 and 72 characters long. If the model has been persisted `password` can be blank or `nil` which indicates that it should not be changed and will be ignored.
 * `username` is required, can't be blank, is unique (case insensitive), and only allows alphanumeric values.
