i am trying to include a jquery file in my module like:

 drupal_add_js($js_path . 'misc/jquery.js');    

but, if i check the page source i see it twice, once in the head section and then the one i included, but, if i remove it, then, there isn't even a single file.

Why is this? and also can someone suggest a good drupal forum, where a newbie can get answers to his issues?

Thanks,
kul.
