Being on this site does not make it a real name.
Clinton is on this site--it's still a surname.
Emilee is on this site--it's still
Emily misspelled.
Zoey is a kre8tyve variation of
Zoe, just like Lyndsi and Britnee are kre8tyve variations on
Lindsay and
Brittany (which are borderline legit in the first place). A "real" name is one that has history, a meaning, and a derivation, for lack of a better word.
Zoe, for example, means "life" in Greek.
Zoey is
Zoe with a Y tacked on.
I'm curious--how are Lyndsi and Britnee real names? Are they real just because people have used them before?
