My apologies to everyone I have ever sent an email to since 1994. I was apparently hacked tonight with a Trojan horse or worm or virus that thoughtfully sent about 700 people an ad for cheap Viagra. I'm sure you thought I was just expressing my concern for your emotional and physical well-being, and not besmirching anyone's prowess. Or implying you were a cheapskate.
It was an error. I have changed my passwords and am running scans to try to track down the problem.
