Module development and code questions

I've been reading forum posts and documentation for a while trying to figure out how to approach the problem of creating a module that will authenticate users based on the result of a HTTP POST request. Can anyone point me towards a module that implements this functionality or give me a quick walk through of how things should work both on the Drupal and the remote site? I can write the code, I just don't know what I should be writing!

In http://drupal.org/node/32185 the author states that the upgraded SimpleNews is compatible only with Head. Was Head at that time a 4.7 version, or has the Head of that time been released as a subsequent iteration of 4.6?

At then end of the day, my question is this: is the current 4.6 SimpleNews download still vulnerable to the multiple copies problem? I had a major embarassment with this problem in December (spammed people with up to 24 copies of the same message) and I wouldn't want that to happen to anyone else.

Hello,

I am writing a module to link Drupal with an ASP I use to do mass mailings and advocacy campaigns (i.e. letters to elected officials).

The ASP provides an API over HTTP to log users into their system. On login, a cookie is returned to the user. When the user browses to the ASPs websites, forms are pre-populated with their data.

The API specifies the following arguments:

Minor issue:

The function node_validate in node.module doesn't allow nodes to have a negative 'created' field.
It's very limiting for my project, and I don't understand the motivation.

Couldn't the following line...

if (strtotime($node->date) <= 0) {ù

... be changed to

$created = strtotime($node->date);
if ($created === -1 || $created === FALSE) {

Not sure I should have posted here... but thank you!
Ciao. Mic

What is the best way to add an image field to a new node type module I am making? Should I use img_assist.module? Or just a form input field of
'#type' => 'file'
? Or what? Thanks!

I'd like to attach a db to my drupal site. I am hoping to be able to somehow mirror drupal's user and profile insert/update/delete db on this external db so that they are in synch. In otherwords, a user registering on the site is automatically registered on the external db: same username, password and any profile info collected. Of course, any updates and deletes also need to be reflected.
