Hello, sounds like I'm having the same problem as everyone else. I'm hoping a Google Engineer will eventually figure out how to solve this, and then go through this thread and notify everyone. Basically, there's a YouTube account "quinthar" with all my videos, and it's attached to either dbar...@quinthar.com, dbarrett%q...@gtempaccount.com, goo...@quinthar.com, or quin...@gmail.com -- I've tried so many things I have no idea anymore. Anyway, trying to reset the password or send a message to the "quinthar" user produces no emails in any inbox, so I'm guessing the quinthar account is just entirely unavailable, along with all content therein. Alas! I hope somebody can figure this out and then email us all instructions.
