I was interested in this website's content and was about to sign up.<p>Then it pointed me to a google appengine sign up page, which says "Google is not affiliated with the contents of the application or its owners. If you sign in, Google will share your email address with the application but not your password or any other personal information."<p>That scared me, I thought I was phished.<p>I checked thinkwithgoogle.com 's whois, it does appear to be a domain owned by google.<p>then the above message is unnecessary. plus this domain does look like a phishing site.<p>you should use something like google.com/thinkwithgoogle or thinkwith.google.com
