I am pleased to announce that Ryuukishi07 has responded to our e-mails and that he does indeed support our translation.
Edit: I had hoped that this would be clear from reading the contents of the e-mail, but it seems that some people have misunderstood. While Ryuukishi07 is encouraging us to continue translating, this group and our patch have no official relationship with 07th-expansion.
Here is a translated copy of his response. Very, very minor spoilers for Episode 4.
