Check if your email has recently been hacked or not. Stupid Corps. and holding all your information in plaintext files. When will they ever learn?
Basically this website has compiled all the recent hack and dumps that various "anonymous" type groups have put upon themselves to carry out. The plus side is, at least you know about the lack of security of some companies and whether you should change your password... since it's already out there somewhere for someone to use maliciously. So yea, if this comes up saying your account was hacked. Change your password to something, at this point it almost doesn't matter what it is. It'll probably get hacked again sooner than later so just keep changing it at regularly random period. Or not.
