Is this weird to share an account?

[The Johnson Family]

Everyone asks what I really am. I've said I'm a boy on some answers and questions, I've said I a girl, I've said I'm 13, 14, 15, 16, and 17 before! Truth is, I'm the 15 year old girl, But everyone in my family has used this account so I've never lied abut my age, My whole family shares an account on Yahoo and we're a family of 14! (12 kids, 2 parents) Is it weird we all share an account? That's why our user is The Johnson's family...

Bonus question:
----------------------

Should we like put our name at the end of something we submit so you know who it is? Like, after I write all this I put -Jaiden M. Johnson or just maybe my first name when I say something and if it's someone else they put their name? Is this system good?

Its Not Wierd But its Better to Have your Own Account and Have it Not Be Shared it Can Be A Security Risk if you Share a Account
