Module development and code questions

Hey I am new to Drupal. My website construction is going well and I have a question

Is there a module that help built in my signature (or certain link or display) to specific nodes?

Complete noob that dive into the deep end. Not sure if this is the right place to post, if not, I would appreciate getting pointed to the proper place.

phpfreechat is the one I am trying to get working.

I believe I have it installed correctly, I can see the mod and I can configure it...but...how do I access a chat room? Or how do I link to the chat room from a menu?

Very confused

Hello everybody!

To start my first post off, I'd like to thank the Drupal community for creating something so great as this. Drupal has been an answer to multiple prayers. OK, on with the show:

Simple question here. I have the log enabled on my Drupal 4.7.x installation. I would like users with "View Logs" permissions to be able to monitor all user activity. However I don't want anybody to see the actions of the administrator. Within the "Log" module, what file(s) would I edit / modify? Can I use an {if} {else} statement? Like:

I'm trying to make a keyword cloud (like tagadelic) of embedded gallery2 keywords as a drupal page. The cloud works great but this code seems to break everything else besides the cloud on that page. Any advice would be greatly appreciated. As far as I could tell, gallery2 doesn't have an API for accessing keywords.

Drupal 4.7.5
Gallery 2.1.2
Apache 2
MySQL 4.1

<?php
function getCloud($minFont=10, $maxFont=35) {
$keyword = array();
$cloud = array();
$my_link = mysql_connect('localhost', 'user', 'pass')
or die('Could not connect: ' . mysql_error());
mysql_select_db('gallery2') or die('Could not select database');

// Grab the tags from the database
$keyword_query = mysql_query("SELECT g_keywords FROM g2_Item where g_keywords!=\"\" or g_keywords!=NULL ORDER BY RAND()");

while($t = mysql_fetch_array($keyword_query)) {
$key_db = explode('; ', $t[0]);
while(list($key, $value) = each($key_db)){
$keyword[$value] += 1;
}
}

// Get totals to use for font size
$min = min(array_values($keyword));
$max = max(array_values($keyword));
$fix = ($max - $min == 0) ? 1 : $max - $min;

// Display the tags
foreach ($keyword as $tag => $count) {
$size = $minFont + ($count - $min) * ($maxFont - $minFont) / $fix;

i'm tring to use the auto-thumbnail but when i chek the auto-thumnail on the admin section i retrieve the segeuent error:

Set correct path for thumbnailer

thanks!

i am developing a VIEW to display some groups teasers.
i want this view to deal/filter by the arguments passed in the GET.
