I just noticed that Ted Ersek has duplicate unregistered accounts, here and here. As he is a valued member of the Mathematica community generally, it would be good to merge his accounts. Does it matter that he is not registered?
Now that he's registered, I've gone ahead and merged his unregistered child accounts into his main, registered one. :D If he has more child accounts pop up, let me know and I'll merge them all into the main account.
