Deprecated - Drupal core

Hello
How can I redevelop the admin interface of drupal so it will be more user friendly.
The thing is that if the client wants to add a menu, he has to create the menu and after he has to give the position of the menu in the site.
I want to find a way so the user will crate a menu or a submenu, or a category in the position that he likes and add the page or the content without doing a lot of configurations.

What is the status of users as nodes in drupal 5/6? i read some talk about this for 4.x but so far it was all just patches, are they their own content type?

the drupal editors automatically convert a full site url, e.g., http://www.mysite.com/???, to /???. this becomes a problem when i send out newsletters, e.g., using simplenews, because the hyperlinks in the newsletter become invalid links. except just manually correct each links in the html editor mode, is there a way to let drupal use the full url to begin with?
thanks,
eric

Is there a proper way to return the current Drupal URL when the URL contains a plus sign? For example, when the the url is http://drupalexample.com/install_subfolder/taxonomy/term/1+2, here are some sample code and respective results:

$_GET['q'] = 'taxonomy/term/1 2'
request_uri() = 'install_subfolder/taxonomy/term/1+2'

What would be the most efficient way to get the current URL (minus the subfolder is present) with an URL with a plus sign?

Dear All,
When i log into drupal, i get my personal web space, where i can view and work on my projects. I would like to implement this on my site too. When a new user is created specific automatic processes should be implemented - like create a working folder, database (postgres), etc. What specific modules of drupal do i need to use to implement this?

Hello.

I need some help.

Here's the situation I'm in.
I want my myModule_loginform_submit function to process the form values in two parallel activities. One of the activities and probably the most challenging one to accomplish is to append the form values to a known url (external page) login form and execute this external page without even opening a browser window. The main objective on this is to get a client session in order for me to open the other pages from this external url without having to login again.
Is this something can be done in Drupal?
