Hi Seth,

I think there is some email client originated confusion here.
I already resolved this issue a month ago with your and Wayne's help.
See https://lists.launchpad.net/kicad-developers/msg37010.html

Is it possible that you actually sent your reply a month ago but it only
was delivered now?
I see a spf record verification error for your domain in email headers.

Regards,
Andrew
