I'm hacked

Apparently people on my address book are getting emails from me with no subject line, containing a link. DO NOT OPEN THAT LINK!

My address book is on Yahoo, so I don't know how it got hacked, but until I can make sure that I don't have a virus (McAfee says no, but obviously something happened) do not even open an email from me that has no subject.

Cool stuff about NTRPGCon later, but I wanted to warn people -- I just discovered this.

Edit - yes, it was that someone cracked my Yahoo password.
