Module development and code questions

I'm looking for a module for Drupal 5 in order to allow some user accounts to administer some nodes.
Some users must have their nodes.
A admin/user must manage the rights.
Which module can I choose?

Hi,

I have a form with a textfield and submit button. I'd like to have the submit button next to the textfield. Not below.

Unfortunately, I can't quite get the alignment right, and have a feeling that <table>'s aren't the way to go. But I don't know how to use <div>'s to get the horizontal alignment right.

Could anyway give me some pointers?

The code I'm currently using is:

function theme_kat_keyword_form($form){

I need these to show real name rather than username. Is it possible to do within the control panel, or I should rewrite the module? Thank you.

How is it possible to remove the signature and timezone fields from user profile edit form?

Hi every body, i know how to make a module with a node . However, how can i make a module with many nodes ? For example, i want to make a module company with 7 nodes (buy,sell,news,fake news,..). All nodes will be presented in the same page like tabs. How can i do that ? Thanks for your supporting.

I am having issues with the Thickbox module not correctly opening images that have filenames with spaces such as: my file here.jpg.

Unfortunately users on my site upload files with spaces and I really don't have control over that I think, or is there some type of way I can fix this so that it works?

Thanks!
