[drupal-support] New sites and db prefixes

Ok - so I have my first site, which has no prefix.. now how do I add another site with it's own prefix? I've extracted the drupal files into a new folder, verified that it has access to modrewrite, and configured the sites/default/settings.php to have a prefix of my choosing, and setup the .htaccess properly. But when I go to the web page it errors out telling me the tablespace for my prefix doesn't exist. The handbook doesn't really cover this that I could find. Hopefully I'm just reading too fast and missing something obvious..? <EOL> Tib
