Somehow I've ended up with 2 IDs. One is AMD Users team founder with 0 credits. The other is the account I created when I joined the project this week. I have initiated the founder request.

How do I remove the 0 score account after I have successfully claimed the founders role?

Unless you manage to log into that account to change things, there's no way to remove the account. Unless Chip believes you and does it from the database.
Accounts are based on the email address. The email address used to make the account is what's the unique identifier in BOINC. So if you have two accounts, you used two email addresses.

The server software this project uses hasn't been updated yet to include the (GDPR compliant) account removal option. But even for that you first need to be able to log into that account. Which can be done by logging out of your present account, try to log back in, choose the "forgot password" option, fill in the email address of the other account. Then check that email address for a login link that can be used for 24 hours.

What you could do there is change the email address of that account to garbage. We don't check email addresses for validity. Do set a password you can remember.
Then log out of that account, log into this present account and change its email address to that of the previous account. That should make you the team founder instantly with this account.

Happy to assume good faith here if all else fails

The problem is that I don't know the email address of the founder account not how and when it got created. I signed up after I saw the new project listed in bok's stats over at Free-dc.org; that is the account tat has requested the foundership transfer and the account I'm running on to earn cobblestones.I'll wait until the founder transfer occurs as the 0 points account isn't going to change to being active.

BOINC really needs to fix this snafu. My guess is the annoying BOINC wide teams which I detest.

That's something chip can look up for you and PM you if you want to.

The option I gave in my previous post makes your present account the founder, not the 0 credit account.

Your team did get made with BOINC Wide Teams. But if you don't want that to happen, why not remove your team from BWT (log in->Your account->Administer->Remove Team->Acknowledge)? You still need to know the email address you registered the other account with for that. And hope it's an existing email address, not a garbage one.

I private messaged you the founder email
