Module development and code questions

I would like to allow some users to have permission to 'administer users', but would like to make it impossible for them to edit the primary administrator account (uid 1).

I would also like to restrict these users so that they have access to the 'configure' tab, but only to adjust the 'settings' (and not access rules, permissions, profiles, or roles)

I hope this makes sense - any ideas would be appreciated. I have tried to modify the user.module without any success.
:)

Greetings All,

This is Ankur Rishi here at CivicSpace Labs (http://www.civicspacelabs.org). I just wanted to announce that we are in the process of building a module for tying locative information to nodes (address.module). The plan is to implement it on top of an API in an include file also part of this project (address.inc).

For details, you can see an implementation plan: http://www.civicspacelabs.org/book/view/5999

For a while I've been wanting a feature similar to LiveJournal's "Listening to" feature to make Drupal an even better blogging platform for nerds like me. I finally finished a thrown together module that I call the "currently" module, because you can put what you're currently listening, reading, or watching in your blog. It integrates with the Amazon Search module to enable searching and showing cover art.

I'm a newbie and can't test it by myself, cuz my hosting server is down atm. Plz check it and correct bugs, thx.

*THIS IS ONLY FOR TRACKBACK.MODULE OF VERSION 1.20, NOT FOR TRACKBACK.MODULE WITHIN 4.52*

Hi, I am trying to redirect the user to a clean node after downloading a file to the user. It works but is producing the normal pre-empted header error in the watchdog log:

warning: Cannot modify header information - headers already sent by (output started at /home/james/public_html/drupal/modules/webform/webform.inc

Here is the code fragment:

I was recently reading about Ohmynews and they have a tipping 'service' which allows readers to make donations to individual authors. As I am aiming to have a similar 'citizen journalism' site, I would love to have this feature.

Is there any way to set up the donations or the paypal tip jar modules to do this? As far as I can tell, they only work sitewide with one account.
Alternatively, would it be possible to create a module to allow people to tip individual users and authors?
