Why two Brad Cox's?

At the top right you'll notice two "Brad Cox" entries with slightly different gmail addresses (brdjcx vs bradjcox). It seems that at some point in the distant past, I created two gmail accounts with these names, and created this blog  under the account that I no longer use (brdjcx). The other is the one I monitor daily (bradjcox).

I've tried everything imaginable to move the blog to the active account but nothing I've tried seems to work. So I ultimately just added bradjcox as a "contributor".
