pmlljl, here's a way we can communicate other than by ITIC message board.
Create your free yahoo email address email@example.com. Then use it to email yourself at your "regular" email address. In your "regular" email address, inspect the email from firstname.lastname@example.org to see that it doesn't reveal more about you than you want to reveal. If it's OK, then you can use email@example.com to communicate with me at firstname.lastname@example.org.
