Drupal 7.x

Hi, I am looking for any advice on the best way to takle this problem. I am working on Drupal 7 (but can reinstall site as drupal 6 if neccessary) and I'm looking for a way to have fields within fields that can be grouped and added as needed. It is probably easier to understand what I'm looking for by having a diagram, so the content type has the following structure (If we take the scenario of a treasure hunt):

Hello
The Drigg/Drupal Vote Module is compatible with the latest version of Drupal?
Thanks

I would like to have on my homepage a piece of text followed by the usual article feed that comes up by default.

In order to acheive this, I have set an article to 'sticky', so that it appears at the top all the time.

The problem is, I don't want this sticky story to be expandable - I want it to be expanded by default. It's just a quick introduction to the rest of the site.

Can anyone offer a solution to this?

Thanks in advance

thanks for helping

I want to implement this hook in my module to alter the urls in this way:
http://mysite.com/users/foo -> http://example.com/users/foo

Following the documentation I have implemented this hook but it doesn't seem to work: the hook is invoked but it doesn't rewrite the urls.

Sorry if this is already covered somewhere, but I've searched as much as I could (even looking through the code), but haven't found anything related to this:

In the install hook of my module, I create a node type and define the fields attached to the type. My goal is to also make this new node type be an OG group type as well as a new book page. The general idea is that when an instance of this type is created, it is a private book for the user.
