Happy Cow is happy
I contacted Happy Cow to check if they would have any objections. Emailed 19th Feb 2017, and conversed with Eric Brent of Happy Cow. I said there was no intention to do any automatic matching or content-scraping. Eric said they had no objections.--Danstowell (talk) 20:39, 22 February 2017 (UTC)
