(Sorry if the discussion if not the best place to post that, but didn't find any better place).
It seems the signup to the http://wiki.lesswrong.com/wiki/ is broken :
Account creation from this IP address (10.254.182.117) has been blocked by Gwern.
10.254 ? Seems that the blocking was made to an internal IP (load-balancer ? proxy-cache ?) so blocking everyone... can anyone fix it ?
