Make always private by default.

Not at this time.

Hi Pippin – Is there any update with this option (to make replies always private by default)? This would be awesome. Thanks.

No sorry, I have not had a chance to do this.

My GD bbPress Toolbox Pro implements Private Replies and Topics. And it has option to set privacy checkbox in topic or reply form as checked by default:
