Delete Project peteypeter

That's not a project, but a user. You can remove it by logging in with that user's email address, and visiting https://launchpad.net/~/+deactivate-account.

Thanks for your fast reply

You're right, but this user might be a ghost. I used it years ago, it was linked with <email address hidden>.
I thought I had already deactivated it, but I might have done something something wrong, and I cannot login any more.

Here is what I've got when I ask to retrieve my password: "No account associated with <email address hidden>"

I've removed it.

Thanks a lot
