Earlier today, I worked for a few hours, with dgg and dlobo's help on IRC, to add a checked checkbox for a particular group to my user registration form, so that people would be automatically subscribed to a mailing list, but could opt out if they wished.

Here's how I did it:

1) Make sure that only the groups you want to show in the register form are set to Public visibility. You can still subscribe people to other groups via the API (such as via the CiviSubscribe module).
2) Create a new Custom Profile and set to be used in User Registration.
3) Add the Group(s) field (which is under Contacts, I believe) to the form. You can give it a different label.
4) Add a hook_form_alter in a custom module to make the checkbox checked. With some help from DamZ in #drupal & cohitre on #jquery, I came up with the following code. It worked for me, at least. Note that $scripts must be in the <head> of your theme, to avoid getting the dreaded "$ is undefined" JS error.

Code: [Select]

function HOOK_form_alter(&$form, $form_state, $form_id) {
  if($form_id == 'user_register') {
      $form['#prefix'] = 
	 '<script type="text/javascript">
	  $(document).ready(function() {
            $("#editrow-group :checkbox").attr("checked", "checked")
          });
	</script>';
	}
}
