Drupal and Vbulletin Theming

[mosphet]

I'm new to Drupal so I hope I'm not asking a redundant question.

I'm working on a new site and would like to know how to use the same theme on my Drupal pages as my VB pages. Is it just a matter of changing CSS or are ther files that need to be changed?

Can someone please detail this for me?

Thanks

It's as easy as modifying the templates for vbdrupal through the vbulletin admin interface
