Yet when I try to sign on to CPDN it says there is no user with my email address. I did sign on with with the same email and created a new account. Is it possible to get credit for past work?

Is it possible to get credit for past work?

Only by signing on as the person who originally created the credit.
The email address is the key to identifying you.

Or have you never had an account here at cpdn?
The Seasonal Attribution Project is a totally separate project. Is this the credit that you're talking about?

Yes, thank you, I just figured that out. I have previous credit from the Seasonal Attribution project. Thank you!
