With the current v1.1.5 it seems the Automated Email Responses are not being saved. I enter the text for an email type, click Save Changes, go to another template, come back, and it's not there.
This could be just a rendering issue, as when I "Load Template" there is no default template displayed for any of the email types.
Just a sidenote: I'm doing this in a new WPMU DEV Hosted site, in a staging area. I have no idea if any of that is relevant.
