Can't logout from this forum

I don’t know what magic is happening here but I’m not being allowed to login to this forum with a different account. When I click logout and then login I keep getting re-logged in with this account automatically, I’m not allowed to enter a username and password. I never even wanted to create this account since I have another long time account, but I was kind of railroaded into creating this account because it pre-filled everything and wouldn’t let me type a different email.

Same here. I click the Log In button and it takes me right inside, without a username or password.

If I try to create a new account, it acts as if my email addresses have never been used, and allows them as new signups.

In my Preferences, it shows a Profile like I have a real account, but apparently it’s not an account.

Very confusing. I would like to convert my Log-In Session to an account, but not sure how!
