Post installation

I want to be able to create a View (using views.module), which will create a Block which contains a listing of other nodes created by the same author as the current node.

If I create an user with limited role and I assign at it only the create and edit page functionally
all ok;
but if I assign also this options: manage menu and manage Parent item it can see also the total item's menu (those of the administrator);if I want that it can to see only the menu that I assign at it or that itself create; how can I to do?

The reason for doing this, is that the editorial staff can more easily edit a drupal page, than a drupal block. So i wanted to load static nodes into "block areas" instead, i'm wondering if there's any performance hits if i do this 2-3 times on a homepage for example?

Here is an example on what I would like my CMS to allow me to do:

- List all promoted or un-promoted posts, or posts in one or more specific categories, or a combination of this. Something like a more flexible content filter.
- With that list, I want to be able to select _some_ of them (check boxes), and perform some CM related operations:
- promote or un-promote to the front page AND assign one or more categories.
- if I need to do that in more than one operation, I need my selection to "stick" so I can perform more operations on those posts

I have an important user that is having problems. I think they maybe coming from her netscape configuration.

This user needs to modify data in the user profiles of other users. When she visits any user profiles the username is changed to her own. I am guessing this is a form fill function because firefox usually asks me if I want to automatically fill out the form. I think her netscape is probably set to always automatically fill out forms. I haven't found this setting in netscape yet.

I've got a project that's using CCK/views to store a set of structured data, and display it in a sortable table. There are a few integer fields, and some of the rows do not have data for those fields. The problem is, an empty value in an integer field seems to get translated to 0 in the DB insert. Is there any way to make an empty value become NULL? I've set the field definition so that an entry is NOT required, but it's not helping. I'm stumped. Anyone have any thoughts?

Thanks in advance!
