You're correct Gail. I'm not an FB user, but I see the dozens that come over to my better-half's email
So I made an assumption...
Just trying to help
As a side-note: The company I worked for instructed all employees to sign up to FB, using their company email addy. I retired more than 15 years ago and never (knowingly) gave FB my home email. Didn't stop it, though. It found my link and my missus gets "invitations" to make me a "friend". One department head lost his job after posting a message criticising his bosses. A true 'duh' moment...
