My current layout looks like this:
LOGO Sign up | Sign In Item1 | Item2 | Item3 | Item4 | Item5 | Item6 | Item7
Once user is logged, the user name appears with a drop-down option for modifying user profile.
LOGO R2D2 (156) Item1 | Item2 | Item3 | Item4 | Item5 | Item6 | Item7
I'm thinking that "Sign up" and "Sign in" is just to close to the principal menu items and maybe I should separate into two rows:
Sign up | Sign In
LOGO Item1 | Item2 | Item3 | Item4 | Item5 | Item6 | Item7
Both rows are fixed and stay on top of the page when scrolled.
