CMS installing cms correctly?
 

would anyone know how to install cms to index page and forum to /forum? my current forum is based around joomla as the index but i want to replace it with vb cms and /forum as the forum page. How would that work out? if i were to move the index.php provided by vbulletin onto my index page to replace jooma then wouldn't i end up not having an index.php for my /forum or if i were to copy it over then i would end up with 2 cms front pages for my forum and index? thanks
