Drupal 4.5.x or older

HI all ,

Im continously getting this error whenever i try to access the link admin/menu

At first I need to add a link to my own PHP script. That link should be displayed in Drupal's menu.

The script (among others) makes a difference in users and cathegorize them into groups in accordance with $user->uid and my own database. I need to offer each group of users different forum or book to collaborate.

I tried to find some help in Drupal's API. There are many helpful functions. But there are so low-level. I need some like:

Hello!

Thanks for the interesting theme GWorks!
I found in the original site www.gworks.ca it's possible highlight active sections, so if I'm in any page in "About us" section, this section in main menu has another color.
How can I dow it in my site?

Thanks.

Hello!

Hi

I have recently upgraded to Drupal 4.5.3-4 on Debian Sarge and have found that all the links I had in my Collaborative book to pages within the book have broken. I had the links in the format of [page title | link text] and now rather than seeing the hyperlink to the page of that title I just see the actual link text. You can see what it looks like at http://www.ngogeeks.com

I am new to drupal.
I got a problem here.
Is it possible that an user can specify the new post blog can be viewed by other users or not?

Or is it possible that an user can specify the user IDs who can or can't view the blog contents he post?

thx a lot.
