*nods* Last names should be reserved until right before meeting, but I think it's absolutly essential to exhange last names at some point! My internet footprint that acutally doesn't exist anyway apperantly name has a first and last name, granted it's my pen name for when I eventually publish, but still! It probably comes from being used to being called by my last name all through middle school and high school and from being friends with multiple Rebecca's, and sharing a lunch table with two of them for a whole year in high school, but I think last names are essential for distinguishing people.
Until one gets to my name.. While my internet footprint is there, one might have to wde through a few references to an eight plus year old, who was connected to some not so nice people and happenings. And he is not related, that I know of..
