And now I'm having second thoughts, both about which the official ordering is, and about the whole name. I'm no longer sure, having just spend $50 on it, that I like it.
Anyway, the current new official name is Six More Degrees. http://sixmoredegrees.com. The logo I'm working on replaces the '[BETA]' tag with 'MORE', more or less. Hence, I also registered sixdegreesmore.*. I'm now thinking maybe I like THAT better.
But, anyway. the .coms were registered last night and should be working for you. the .orgs and .nets were just registered and won't be up for a while (I haven't even set up DNS for them yet).
For now, they'll all redirect to sixdegrees.martian.cx, until I figure out a good way to switch over the cookies.
