That's highly unfortunate.Unfortunately I am blocked from that site for reasons that nobody can explain.
I have sent numerous inquires using various methods and email addresses, and for whatever reason, they don't respond.
The site is mostly blank for me other than text.
Wish I could see it, but perma-blocked apparently, and no way to get a response from anyone on that site.
As I mentioned before, its a closed club, and items posted there are not necessarily visible to outsiders.

Roger helpfully shared some fantastic R&D here
