I've been having this problem for a while. Whenever I go to the forums as Anaguum, I have to sign in before posting. One time when I tried doing this, my password didn't work for some reason so I requested a new one. I got it and that one worked for a while, but then I was off my CPU for over a week and so forgot it. I've tried requesting other passwords but none of them work. I've also tried changing them in settings, but still no luck.
