OK, including myself, there are now 8 people on the whitelist (there are 2 places to enter names, and I may have done the wrong one at first, but now everybody is in both to be sure).
Just puttering around spawn, gathered some sheep, chickens and cows, and a small wheat farm going. Plus I got a carrot from a zombie almost right away so have 4 of them planted at the moment.
I've gotten some occasional block lag, but that might be on my end with the connection, but otherwise, seems to be running smoothly.
