People who are criticising this dont know anything about internet security. The password you had yesterday could have been monitored, and so by changing it today, your account details havent been hacked. And if your forum password is the same as your facebook/email password, someone could have access to your whole online life. Extreme and unlikely scenario, yes, but it is possible.
Also, please dont make your password 'password' or any variation. You almost deserve to have your account hacked if you do that. And try not to make your password Eurovision related, it's too obvious on this forum.
