I'd like to blame Friday the 13th, but actually, the issue started yesterday.
It looks like the Savvy Authors site, where I am currently giving my Beyond Fangs writing class, has been hacked. Many people (me included) have gotten "Malware Warning" alerts from our antivirus software. I'm still waiting for official word from the SA people, but I'm sure they're working hard to fix the problem.
In the meanwhile, if you're taking the class, you have my profound apologies, and my assurance that one way or the other, we'll finish this dang thing.
