Module development and code questions

I know that there are a few workarounds for this, but I'd like to get a Group hierarchy module developed that allows top level groups to have subgroups.

What should be included:

I am using workspace and cck to make a list of everything a user has created. when workspace displays my custom made cck nodes there are no operations next to it (edit, delete) but when it displays the page node the operations are there. i'm sure it's just a simple setting but does anyone know how to display the edit and delete operations next to cck nodes in the workspace module view?

I see the module Sitemap in site drupal.org used for Drupal, but when I set it up for my site (on localhost), it doesn't work.
How can i fix this problem?
Please help me .
Thanks!

Hi,
I have been working on an updated version of htmltidy, but, crazy as it sounds, the module does not work properly if the user is not logged in as administrator.

If the user is not logged in and is using Internet Explorer of Firefox, only a white page will be displayed. Instead, works correctly with Opera and Curl (and some other file fetching tools).

Any suggestion? I have of course cleared the cache.

You can see the module here: http://drupal.org/node/80160

I want to display everything a user has posted, basically display a list. I found this snippet:

http://drupal.org/node/63965

and cannot get it to work. Does it not work in drupal 4.7? What I did is create a page, pasted the code into it, and then click php as the type of page. After I did that it dispalys a blank page. I'm guessing I'm missing a step.

I want to take an argument from the URL, ie: http://localhost/?q=node/add/retailer/12345.
And be able to use 12345 in the retailer_form_alter hook.
Can this be done?
Basically if this argument is not provided I want to display a message instead of the form?
Any help would be appreciated.
Cheers
