Hide Forum Header

[lynx31]

Hi,

Just starting to set up our VBulletin forum.

We have a title header in place (a logo at the top of the forum). The only concerns are, is it possible for us to 'hide' this header when the forum is locked down / to those people who aren't members. The Forum is intended to be private staff company forum so we'd rather someone not stumble across the locked down front page, be unable to get in but still be able to see what the header is? Despite getting everything set up and searching around I've not been able to find anything that'd do this (maybe I'm overlooking something really simple?)

thanks
