Question kunena adaptation to templates

Hi there:

I have the following site just trying to setup kunena as a forum.
test.carlosfenguix.org/cmuntanya/index.p...om_kunena&Itemid=122

It looks really bad. My template has a header section, a left column section, a main section where it is displayed kunena and a right section.

The whole template "gets destroyed". For a person with very simple CSS notions, what are the solutions.

I want something exactly as you have at your demo site. The main page has several module sections and later on kunena appears at the whole main section.

Which css files (both my template css and html files and kunena css files) I have to modify and which parts?

Or can I display kunena out of my main joomla template as a whole page?

Cheers for a pretty lost and forum beginner user.

I say this often. If this does not happen when the default Joomla templates are selected then your Joomla template is the problem. The fix could be simple or not depending on how good/bad your template is coded. My suggetion would be to get a different Joomla template.
