Drupal 7.x

I managed to get the multi-site working following the instructions on this page: http://drupal.org/node/463262

I was able to remove the description from below the Username field using this:

function custom_form_alter(&$form, $form_state, $form_id) {

switch ($form_id) {

case 'user_register_form':

$form['account']['name']['#description'] = t('');
break;

}
}

but I don't know where to find a list of page elements to alter any other aspects of the User Registration page.. or any other page for that matter.

I am new in Drupal field.

I want create a page that includes quizzes having values like True/false in radio button, if select true - AAA.... message will display and if select False- BBB... message will display.

I used Poll module, but it doesn’t have feature of displaying message after selecting a specific choice. I am not getting how I can do it.

Please let me know if anyone knows about it.

Thanks

I installed Drupal 7 and now it's telling me I need to install PHP extensions for dom. I downloaded the rpm and installed it, but the Drupal Requirements page is still complaining. Any thoughts?

the style and the layut of ckeditor of drupalgarden.com is obviously the best editor i know. i wanna know how can i have the same in my site. i tried download the theme of a drupalgarden site and use it in my site. but it doesn't work. anyone knows how to? thanks much.

This happens every time I select a custom field from a custom content type used when created in a view.

Fatal error: require_once() [function.require]: Failed opening required '/home/content/28/5027628/html/home/sites/all/modules/ctools/includes/fields.inc' (include_path='.:/usr/local/php5/lib/php') in /home/content/28/5027628/html/home/sites/all/modules/ctools/ctools.module on line 111

If I select the Node:Title field I get this (but it still lets me modify the settings):
