Hello forum,
I already have an account on this site and I've had it for quite a while now, and I registered that first, original account with, let's call it "email address 1". Just now I tried to log in here, but I forgot that I used email address 1 for that account, so I accidentally used email address 2 instead, and typed in some random password that I thought might be the correct one. Surprisingly that seemed to be the case, but somehow my name was suddenly different. That's when I realized that was not my original account, I had just logged in to a different account that I didn't remember ever creating. So I looked into this accounts settings, and it said that I had just created it, but I never clicked on "register", I definitely 100% clicked on "log in". I didn't even receive an e-mail saying that I created an account here, it just suddenly somehow came into existence?? What the hell happened here? oO
EDIT:
I just remembered that I had used email address 2 to register Avast when I first installed it - directly in the program, not on a website or forum like this. Could it be that if you have such an Avast account, and you try to log in to the forums here with the same email and password, it automatically creates a forum account with the same data? That would be my only explanation, but I don't know if that's actually what happens.
