Answers.Text: CiviCRM will allow it to pass with one *or* the other or both tokens. And, a little "Duh!" on the default Opt-Out message. You are correct. And, thank you for the patch. Great work!

Body: <p>When "SEND TEST" buttons are greyed out there is no notification as to what is missing from required fields to be NOT NULL. By default if "Opt-Out" token is not included in the message the "Opt-Out" response is left NULL but is still a required field that cannot be left empty. Choosing the only default brings all the buttons active. Please advise?</p>

  (Asked by: username_0 on 2015-05-19)
  
  When "SEND TEST" buttons are greyed out there is no notification as to what is missing from required fields to be NOT NULL. By default if "Opt-Out" token is not included in the message the "Opt-Out" response is left NULL but is still a required field that cannot be left empty. Choosing the only default brings all the buttons active. Please advise?

  * There shouldn't be any connection between the "Opt-Out"/"Unsubscribe" token and the field "Responses: Opt-Out Message". Both are required.
  * If the "Opt-Out" token (or "Unsubscribe" token) is missing, then you should get a very loud error message. (The token is generally provided as part of a header, footer, or message template, so that you don't have to put it in explicitly.)
  * The field "Responses: Opt-Out Message" should be filled in by default. If it's not, then perhaps someone removed the default. Try navigating to "Mailings => Headers, Footers, and Automated Messages". Edit one of the "OptOut" messages and set it as default.
