My Question or Issue
I am not sure how I created my account years ago, but I believe I signed up with facebook. My account settings still have my very first e-mail which I do not use anymore. When I sign out and sign back in, I can do so with Facebook. However I cannot change my e-mail adress, detach my facebook account or even change my username (which is a number at the moment).
How do I change these settings? I would like to detach my facebook account, my user name and e-mail, but how?
