Module development and code questions

I have developed an extensive library of company policies, procedures and knowledge base using MediaWiki. I would like to integrate this content into our up & coming drupal installation. Ideally I would like to maintain the MediaWiki syntax (so I don't have to train the users on new syntax).

As a result I have a few questions;

just today I overhauled clipper

I have the following items defined in hook_menu():

$items[] = array('path' => 'case/calendar/week',
	 'title' => t('calendar'),
	 'callback' => 'case_calendar_week',
	 'access' => user_access('view calendar'),
	 'type' => MENU_CALLBACK);

$items[] = array('path' => 'case/calendar/week',
	 'title' => t('week'),
	 'callback' => 'case_calendar_week',
	 'access' => user_access('view calendar'),
	 'type' => MENU_LOCAL_TASK);

I need to append an integer value to the defined path. For example:

Hi All,

Just made a start on the Drupal module development
(http://drupal.org/node/17914) tutorial but have falled rather heavily

Hi,

I made a modifaction on profile.module to add a link like "user list" which is only lists "online users"...

The main idea was to copy the fuction on profile.module called "browse_profile" as "browse_profile_online" and change the sql query to select online users...

so that the line

$field = db_fetch_object(db_query("SELECT DISTINCT(fid), type, title, page, visibility FROM {profile_fields} WHERE name = '%s'", $name));

has to be changed to select for online online users...

Hello,

i have installed banner module on drupal 4.6.3 and all banners are shown. Also the statistic counter from all views are shown to me as administrator (all banners are set to owner 1)
My Problem is now: there are no Clicks counted. I have set the Maximum total clicks: 0
what should mean that the banner is allowed for unlimited clicks.

In forums i didnt found an answer, please help if you know how to fix it.

greetings from germany, holger
