How do I eliminate a duplicate account?
During sign-in I created a duplicate account. I backpaged to make a change on the registration form.

Hmmm, hopefully it’s not possible to create a duplicate account with the same user name as a key. Did you receive a web page confirmation of your account ID or an Email to the Email address you registered your user with the following details?

climateprediction.net URL: http://climateprediction.net

Your account ID:

Where your account is a unique alphanumeric string.

Maybe your account is not activated yet and can be via the http://climateapps2.oucs.ox.ac.uk/cpdnboinc/account_created.php link, presuming you know your account ID.

I received 2 comfirmation letters with different passwords.
It appears that I probably have only one account. When I tried to use the password in the second comfirmation letter I was unable to sign in. I got a sign in failure.
