There should be an email where you can lock your account if the password or email is changed (as far as I remember; correct me if I'm wrong). Better post in Meta and sign a message then send it to Cyrus or theymos.
Can we change our password using with our email? Im just worried on my account ive logged in to my lost phone. I don't know weather someone use my account for dirty purpose. I need to know to avoid circumstances like this. Its hard to make a new account now when you're ip address is being used. Just lucky to have an account in this forum.
