Adressing STDs Question...

This is a two parter...

Did you guys include '& guest' for your single guest's STDs when you mailed them out??? Or can I leave it off for an STD?

What about people who are in new relationships... for my friends who have been in long term relationships I am including their BF/GF's name but for instance FBIL just started dating a girl a month ago I was going to leave her name off... I've never even met the girl. Is that ok?
