I am not sure how to do this...

I do not want the "gallery" or Ventrilo available for the general public to view...I tried looking through everything and I cannot find a way to make this "guild only"....

You can do this by heading to Admin > Menus > Menu Administration, and then editing the particular objects to choose the appropriate ranks.

Also, you can edit subgalleries and make individual subgalleries only viewable to certain ranks.

Does that make sense?
