I'm part of the beta. Some of it is taking some getting used to. I only had a few days to play with it before coming to Vegas. Will dive in more when I get back. It definitely does multi-level joins. I've gone as deep as 4, but I have some crazy searches in mind that I want to try out when I get home.

Can anyone join the beta?? I was interested in multi join back 3 years ago when they announced it??
