Display category and gallery only after log in

[!@#$%]

I'm just start working on my own Coppermine v1.3, got some questions and still cannot find the answer from old post.....

1.)  Can we modify to hide category and gallery in the front page?  Only display after log in.

2.)  Can we hide the colume "Random files" and "Last additions"

1) Don't post the same thing 5 times
2) If you want support, don't post in a board named 'General discussion (no support!)'
3) Use a sensible name
4) Read the manual
