CMS Made Simple Forums

I'm wanting to use CMS Made Simple for CMS of data to be entered into an existing db. Do I need to write a module for this?
I only know basic php. The modules look intimidating.

Basically, I want to use the CMS Made Simple part so I can keep track of users and what they update.
I'm not sure how to incorporate my db into CMS Made Simple.
Here's what I'm wanting to do:

a. user logs into CMS
b. user goes to a template. this template is a structured form.
c. they fill out the form, press submit and the db is updated.

So, how do I do this? Can you point me to some readings?

TIA

This is definatly module territory.  There are 2 articles on writing modules here and here to give you an idea of what's involved.  Also, CMSMS does not support logins in the frontend by default.  Your best option would be to used the UserID module (found here) as a dependency to give you the user login ability.

Make any sense?
