I keep getting these notifications from Frienster and I never created an account. I know somebody is using my email. How can you notify Friendster? I don't really understand what to do. So shouldn't the guy who activated his account on my email know my password? I changed it immediately after I saw Friendster notifications. Somebody help!

Edit: 1000th post! On a thread created by me too. I didn't even know. =D
