Drupal 7.x

Im a Drupal newbie and just starting to try out a little module development.

I want to make a module which needs to add some extra user information about each user when they sign up.
I see there is a hook_user_insert(&$edit, $account, $category) which gets called when a user is registered, but Im not sure how to get my own fields into the '$edit'-parameter.
Can I add custom fields to the default signup-form or do I have to create my own signup-form? And how would I add custom fields or create my own signup-form?

Thanks in advance for any help!

I have been working on the site to upgrade it from drupal 6 to drupal 7. Here is how I am able to do it.

While going through the video tutorial for configuring OG, I came up with an unexpected issue. When I went to "add content" I found that the option for "articles" wasn't listed. I've tried to look for info regarding this issue, but have yet not been successful. Can anyone please tell me if there's an option I need to enable that I've somehow missed?! I just cannot see what I have, or have not, done!

Many thanks!

Hi everyone !

I have a little question with no answer, yet.
Although I looked for in this forum I don't find how to resolved that.

Actually, I have a form called by a hook_menu (inscription/%/pre-inscription) which callback a form defined in my inscription module.
In this module there is a block, built (info et view), which is used for display some values from $form_state.

In fact, my form is composed of several steps, and I want to display to the user his informations from last step.
