A couple of users have asked us why we open a Safari session when you select "Send Message" from the Web and AppStore applications. The short and easy answer is that we needed to provide a mechanism that would be consistent with Microsoft's very strict rules surrounding Passport/Windows Live logins. We wanted to provide the functionality without running afoul of their policy.
At 1337pwn.com, we will never ask you for your Live/Passport login information. It's not a matter of technology -- it's compliance with Microsoft's requirements. I hope that this clears it up.
Thank you for your support and feedback!
