I apologize to anyone who received a strange email from me last night.......I didn't send it. My daughter says that it means that my email was hacked. I got notice of some addresses to which it failed to deliver, and I couldn't make out the message that had been sent. I have changed my password and hope that it won't happen again.
I'm assuming that the title of the email was "no subject". I've gotten those before and when I opened them, they sent me to sites selling Viagra and such. I no longer open any email with that title.
