Module development and code questions

I am working on a classified ads module that integrates with Drupal, and possibly release it to the drupal community if there are sufficient interest.

How would I go about tweaking my user page so it displays people's interests as links and keep them all categorized in a taxonomy type structure like on drupal.org? If you go and view my profile here: http://drupal.org/user/42008 and then click on one of my interests it will then take you to a page with everyone else who has the same interests. Does anybody know how this could be achived?

Thanks!

I'm sorry that I didn't really know where to post this, but is there a module that I can install to allow users to comment on other users' profiles? If so, is there a module that has to be installed so that module can function correctly?

Thanks

og module for forums, freetagging, taxonomy, access i18n and probably more that I don't know about. These modules all have new, old , conflicting and not working patches are just glorified hacks to the core. Yet they all have contrib status. Add to the confusion with the fact that a patch only applies to a certain version of a module and the modules have no versioning. To the average joe like me this is all very confusing and impossible to fix and keep track of.

There's got to be a better way!!!

Is it possible and how, do I create pages within the modules script?

You have the normal pages...form, main, settings, etc. Plus, I have a custom overview page.

But, how do I add more than one custom page?

I am looking to try and achieve 3 things with the recent comments block:

1/ Have the node title displayed above each of the recent comments in the recent comments block.
2/ List (eg) 30 words of each comment
3/ Get rid of the time stamp

The code in the comments module that i think must be tweaked is this:

/**
 * Implementation of hook_block().
 *
 * Generates a block with the most recent comments.
 */
function comment_block($op = 'list', $delta = 0) {
  if ($op == 'list') {
    $blocks[0]['info'] = t('Recent comments');
    return $blocks;
  }
  else if ($op == 'view' && user_access('access comments')) {
    $result = db_query_range(db_rewrite_sql('SELECT c.nid, c.* FROM {comments} c WHERE c.status = 0 ORDER BY c.timestamp DESC', 'c'), 0, 10);
    $items = array();
    while ($comment = db_fetch_object($result)) {
      $items[] = l($comment->subject, 'node/'. $comment->nid, NULL, NULL, 'comment-'. $comment->cid) .'<br />'. t('%time ago', array('%time' => format_interval(time() - $comment->timestamp)));
    }

    $block['subject'] = t('Recent comments');
    $block['content'] = theme('item_list', $items);
    return $block;
  }
}

From looking at the code above, would i need to add to the $result query to SELECT title FROM {node}? How would i actually code that in?

With the length of the recent comment itself, where can this be altered?
