I've never heard of this either, but would be really handy to have! Do you have to ask them to join the list?
Totally agree on your other points! I'd also really love a Centurion House in central London, like the one in NYC, but I don't see that happening soon. The travel benefits really need a spruce too.

Not sure if they will send automatically every week. Seems you have to ask each time. Even if they just updated it on the website periodically, better than is now.
One can only hope for a Centurion House!
