Divaster strikes, Navigation bar confusion! Options

[nvek]

This might like seem like the dumbest question yet, besides what's an url!

Can someone explain the navigation bar for me? I've become very muddled up on this part despite digging around for answers in tutorials and forums.

I'm thinking that it's the home, browse, search... but does it also include add me, message me, block me.... Are these essentially ALL just links that get covered up in the overlay and you have to put them all back in?

Is there any way to display the navigation bar (I'm imagining a script that somehow prevents it from being hidden) or do you have to make your own navigation bar if you have an overlay?

If thats the case then why are the separators visible when the links are not (which is how mine looks)?

And this part I really don't get: if you make your own navigation bar then how do you make sure that the link to 'home' always brings people back to their own home should they drop by?

Sorry if Im being an idiot!
