nibbler as far as i have found out their site is suppose to be live at 5 pm ( time zone unsure of ) All domain transfers from them need a EPP or Auth code and they seem to be hard to get at the moment . If you want to keep yourself updated on whats happening check out
www.registerflies.com they seem to be keeping up on the news . i am camped out there now lol hoping and crossing my fingers so i can get my domains transfered ASAP
hope this helps
