I got the email about the transition. Since I had an account for a long time they sent me an email with a special link. I clicked on it, it asked me to change my password, but then it kept telling me the old password was incorrect. Then I accidentally deleted the email with the link. So I have no idea how to get in, who to email, or what my old password is, or if I successfully changed it!
I tried to communicate through the chat link they sent, but nobody was available. Very frustrated.
update: found the email, still can't get in.
