I wonder what this means and whether it's fatal.

How do I fix it?

I suspect it's something to do with my action yesterday while attempting to reply to a thread from HyperKitty. The superuser account uses my address - odhiambo at gmail dot com.I am also the listowner for most lists. I tried unsuccessfully to create an account on Postorious using the same email address. I kept getting sent links to verify the account, over and over. Finally, I was able to verify the account, but cannot login with it.
