no navigation bar for guests --> navigation bar for members only ???

[stormtrooper]

hi ya!

I've just installed CPG 1.4.6 and changed the theme a little bit.
The gallery is bridged to Invisionboard 1.3.

What I'd to have is, that a guest can only see the gallery without navigation bar.
But people logged in to the Invisionboard can see the navigation bar.
Where is the code where I have to differentiate those two curcumstances?

greets

one solution would be to copy function theme_main_menu from themes/sample/theme.php to the theme.php you're actually using and modifying it to your needs
