Unfortunately not all senders realize that their emails are tantamount to Baked Beans, so my mail box is protected by comfirminator.com.  When you send an email to the above address, you will receive an automatic reply asking you to visit a web page and click on a button.  This will prove that your return address is valid and drastically increase the odds that I want to hear from you.
