Drupal 6.x

I'm planning to make a to do list application based on drupal with a simple scheduler... (time, date due)

I'm wondering, could I make it use jquery and mootools with a scheduler..
and then turn off all the other modules. this to do list app will allow a user to select 'in progress', 'done', 'pending', etc.. per list.

I'm not sure where to start, like should I just use the Blog module and make comments to whether something is done or not.. then how to make it list everything in one page.

I and a few others are working on creating a module that will send SMS messages to a users mobile device using the drupal powered sites email address. It's an API that stores a database of mobile operators and their email address(i.e. Alltel @paging.acswireless.com). It has four parameters that other later to come modules use in order to send messages from anywhere on the site. It doesn't need a mobile gateway such as click a tell... Your Drupal site just must be capable of sending emails.

Can I change to email and password login? If possible, how?

GD library Not installed
The GD library for PHP is missing or outdated. Please check the PHP image documentation for information on how to correct this.

I got this error on installation, i delete the comma at the beginning line for that library in php.ini files but this error message still.

How i can resolve this problem???

...never complete"

Here's the situation:
I've done a fresh install of 6.0, then an upgrade to 6.1 on a new site.

The first item of content I created was the "about us" page as content-type 'page' (node/1).

I've got the path module activated, and the pathauto module installed but no longer activated (in the process of troubleshooting, I have disabled it).

I've also got the global redirect module installed and activated.

Hello everyone, I am trying to speed up my drupal website and I spent last 2 hours trying to find out how to get number of sql queries that were executed on current page, could you help?

Only useful thing I found is the $queries global variable which should contain number of queries, but var_dump($queries) prints NULL in my case :/.

I'm using Drupal 6.1. Thanks for any idea!
