Just FYI: Here is some great advice about how to handle intimidation.
Someone thinks I sent them an anonymous email. Why on earth would I do that? I am not afraid of you! If you are frothing at the mouth about some anonymous email you received, it did not come from me. I’m not afraid of people who rant about communism and issue threats on the Internet. Only cowards and unstable people would do that kind of thing.
