Module development and code questions

I have xampp installed with Drupal 4.7b5 running. I have Mercury Mail running. But I'm missing something in the mail setup that's producing the error below:

warning: mail() [function.mail]: SMTP server response: 550 Address '' not known here. in C:\XAMPP\htdocs\drupal47b5\modules\user.module on line 400.

I think that once I get this problem resolved, I'll have a local install up and running, but at this point, I'm lost and need some guidance. It's probably a really basic setup step that I've missed or messed up.

I would like to extend the taxonomy_context module through another module.

Presently, taxonomy_context creates an index page for each term. This index page displays titles and descriptions/teasers of nodes/terms belonging to the present term.

I want to create a feature where a single node can be designated as the 'node index' for a term.

Example

I have a term 'Science Instrument'. There are six story nodes that belong to this term. taxonomy_context will create an index page listing all six nodes:

http://kalawe.com/images/support/drupal/indexBefore.gif

I don't want this. I want taxonomy_context to only display the title and body of the node designated as the 'node index':
http://kalawe.com/images/support/drupal/indexAfter.gif

Code

I've created a new table 'node_index', with a single field 'nid' which is the node id of a node marked as an 'node index'.

It would get the term's id using the taxonomy_context_get_context() function:

$context = taxonomy_context_get_context();

This db query will fetch the proper index node:

SELECT gem_node_index.nid,rev.title,rev.body
FROM term_node,gem_node_index,node,node_revisions as rev
WHERE
term_node.tid=$context->tid
AND
term_node.nid=gem_node_index.nid
AND
gem_node_index.nid=node.nid
AND
node.vid=rev.vid

I don't want to hack the taxonomy_context module. How do I go about creating a new module to modify the term index pages taxonomy_context creates?

Hi, trying to use the OG modul with 4.6 I am getting an error, when I want to approve a user subscription to a group:

call_user_func_array(): First argumented is expected to be a valid callback, 'og_approve' was given in /var/www/drupal/includes/menu.inc on line 354.

maybe anyone knows about this?

I am trying to format my table so that the rows have 2 lines of data like below:

1234 John Doe
anything anything anything

here is my $rows[]

Hi everyone,

Well this is my first post. :) I would like to began by thanking everyone who has worked on Drupal to make it what it is today. Great CMS and I'm glad I stumbled upon it.

My question is concerning the Taxonomy Theme. I'm able to specify a theme to use with the admin section of the site but I'm finding that I'm not able to specify one for the add content (?q=node/add) section. Is there a way to go about this with Taxonomy Theme? Or will I have to look at other options? Any links would be helpful as well as explanations. Thank you for your time.

I am new to using theme_template and it has me a bit confused. The following function breaks my site i.e. module including this function is activated the site displays only blank page. Remove this function and all is ok. I am piecing this together an don't understand all of functions it is using yet so I am hoping someone with more experience can help me fix this. Once I have it working I am sure I can back into how we got there.
