Module development and code questions

Hello,

i am thinking in porting my application Cm2F, which allows to integrate mailbased communications with forums, and i was wondering which forum softwares are being used with Drupal.
Are people using the standard Forum module, or are they installing any other solution/ports of other well known forums?

Regards,
D.

There is a feed overview in
administer -> aggregator -> Feed overview

The problem is it lists all the feeds. Is there no way to display only feeds by 1 category ?

It would be nice if I could just switch categories and drupal will show necessary feeds what are exactly in this category what I clicked and not all feeds(could be about more than 400) at once.

I tried the module "onthisdate" of the tutorial.
The module create a block but the block of my new module does not appear in my pages.
Can you help me please.

this is the module :

<?php
function onthisdate_menu() {
$items = array();
$items[] = array('path' => 'onthisdate',
'title' => t('on this date'),
'callback' => '_onthisdate_all',
'access' => user_access('access content'),
'type' => MENU_CALLBACK);
return $items;
}

function _onthisdate_all() {echo "bonjour anis";

} // function _onthisdate_all

function onthisdate_help($section='') {
$output = '';
switch ($section) {
case "admin/modules#description":
$output = t("Displays links to nodes created on this date");
break;
}
return $output;
} // function onthisdate_help

function onthisdate_perm() {
return array('access content', 'access onthisdate', 'administer onthisdate');
} // function onthisdate_perm

function onthisdate_block($op='list', $delta=0) {
// listing of blocks, such as on the admin/block page
if ($op == "list") {
$block[0]["info"] = t("On This Date");
return $block;
} else {
// our block content
// content variable that will be returned for display
$block_content = '';
// Get today's date
$today = getdate();
// calculate midnight one week ago
$start_time = mktime(0, 0, 0,$today['mon'],
($today['mday'] - 7), $today['year']);
// we want items that occur only on the day in question, so
//calculate 1 day
$end_time = $start_time + 86400;
// 60 * 60 * 24 = 86400 seconds in a day
$query = "SELECT nid, title, created FROM " .
"{node} WHERE created >= '" . $start_time .
"' AND created <= '". $end_time . "'";
// get the links
$queryResult = db_query($query);
while ($links = db_fetch_object($queryResult)) {
$block_content .= l($links->title,'node/'.$links->nid) . '

what forum can be put in drupal

What happened to the organic groups module? I just upgraded from an earlier version and now I am so confused. Everything has changed.

Dear Forum,

Ok I'll try and make this as concise as possible given my limited knowledge of module development.

----------------------------------------------------

-What I would like:

1) A very simple module that allows a user to upload a word file or pdf file and that reaches the admin email (i.e. my email).

2) That this module would be displayed unter the 'create content' section in the user panel.

-What I have already:

1) I have the upload module installed so uploading is not a problem.
