As you can easily see when you visit LessWrong.com, the site transfer is complete, and we are now on the new URL. The data import will run for the next few hours, and by tomorrow morning everything should be complete.
Let us know if you run into any problems, find any broken links, or anything of that sort!
Hmm, this could be the bug that's seemingly resulting in a number of LW1 ("legacy") accounts being locked out. Did you have a recovery email set on LW1 before the first database import? If you didn't, but perhaps set it later, then make sure that you can request a "reset password" email from https://www.lesswrong.com with that address (don't worry, this won't actually reset your password or anything unless you click the link in the resulting email message). If you see an error because your recovery address can't be found, visit the "edit account" page in your logged in session and resubmit your data there (your email should be there, but resubmit anyway), then retry the "forgot password" feature on lesswrong.com and make sure that it works for you. This should hopefully ensure that you can always upgrade your account, even if you get locked out from LW1 logins.
Strongly agree. I messed up some of the login error messages myself, and we should fix that very soon.
