I have a few friends who joined here 2 years ago and they want to find out their username and password again on here. I saw a few of my friends' names on here but then a few days later their name was 'Anonymous'. When I went to click on Anonymous, it said this user isn't on our system anymore. Can someone tell me why this is happening? Is this just how Question.com works?

Sincerely,
Scy Notley
