I use customer authorization on my site and only want those customers who are pre-approved to be able to see the categories. I know how to turn off the categories tab in the layout settings, but I just want them hidden UNTIL a customer logs in...? The only other thing I can do is hide the header under a customer gets approval but I'd still like our logo to show, so I'm not sure how to get the best of both worlds.

Anyone have a suggestion?
