Thanks for this.
Odd thing, though: when I tried to connect to their site, I got a message indicating that I was blocked!
Sorry, you have been blocked

WTF?
After a few more tries with different browsers, I figured it may simply be my location (Canada), so I turned on my VPN, connected to a server in New York and, SURPRISE, I can reach the site.
I suspect they don't want to deal with non US.
