The links in the menubar, like on this site. What do I have to add/edit to space the links further apart.
On one skin I'm adding, the links seem jumbled together.

how are they organized? In a table or what?

No, just inside a menu div, quite similar to here.
It uses the <ul><li> tags.
Can I add spacing in the css for the menu class?

EDIT: Actually, it's a modified default template, so i'm pretty sure it just uses the default menu arrangement.
