Do you still want to have vbulletin in the /forum directory or do you want vbulletin to be in the root? If you want vbulletin to be in the root, then you need to move all the files from the /forum directory into your root directory. If you just want your domain index to redirect to your /forum directory then you can either make a copy of the vbulletin index.php file and put it into your root. Modify it per the instructions in the file to point to your forum page. Or, create an .htaccess file to do the redirect.
