Further to this thread regarding having two CPIDs https://boincstats.com/en/forum/21/12089,1
I go by the same user name on every project, with the same email address, but I've lost access to the account with that same user name here and with it all the stats under that account and the ability to connect it to my WCG account which works on user name rather than email address.

How can I regain control of my account?

I am perfectly happy to have this account deleted and provide whatever information required to gain access to my original account but as I no longer have access to my old email addresses I will need help from an admin.
