Basically I have a custom contact forum currently working but came across an issue. One of the questions I ask can have 1 or more answers to them so instead of having a text field or menu, i created multiple checkboxes.

This is the code that I have for the body of the email:

Hi all, I'm new with Drupal development, and so far amazed with how easy is to hook up into Drupal's framework to build modules.

I'm trying to write a module to import a list of users to drupal (a CSV or XML file with some custom fields that will be mapped to custom profile fields), and trying to use this project to learn how to build modules.

I already built the skeleton of my module, made the form and added an input 'file' into the settings form. What I would like to do now is to save this file into the server, so then I can process it to create all the users. I cannot get where is there I can access the file data to save it.
