The "undefined index" thing should've been fixed as of last night. I moved to a new apartment over the weekend, and I've barely been online. As soon as I got the computer hooked up at the new place, Texas went through "rolling blackouts" because apparently the idea that water turns solid below 32f is new to the power company.
As for IPv6... if/when softlayer (the datacenter I'm hosted with) provides it for free, I'll support it. I won't pay extra for it though, as it's useless to 99% of people right now.
