I want to use a different version of the XOOPS template for the viewtopic.php in newbb

In case your wondering I want to remove the right side blocks and increase the content width without ruining the site's design but I only want this to happen on the viewtopic.php page in newbb.

What I would like a kind person to tell me is:
Newbb seems to be different, not the usual include mainfile and header, what file does contain the information setting the content to view inside the XOOPS template.

thanks



EDIT: would the same effect be achieved if i just copied the theme but changed the theme template for the clone and used that theme for only the forum...and how do you set a theme change for a module?

Nevermind

i'v just done it the easy way and changed the theme for the entire forum, rarther than hack into ceperate pages
