Solved Change width of default template

I was using Joomla 1.5.x and Kunena 1.6.3 with default Blue Eagle template.
Now using Joomla 2.5.x and Kunena 1.7.2, i see difference in the width of the template.

First screen is the old default template

The second screen is the new default template

How i can have the width like in old default template.

I tried to modify components\com_kunena\template\default\css\kunena.forum.css in the main section from

to

Any help?

ok i found the right css to modify with Firebug, solved!

and the answer was... LOL i hate this posts.

Edit the css.

Here is the entry:
#Kunena {
min-width: 700px;
}

Just change 700px it to whatever you need.

Or add this with your changes to anywhere you like in the css:
#Kunena {
min-width: 700px !important;
}

A word of caution whenever people read "edit the CSS" and especially where they may read "anywhere you like in the CSS": see msg #7 in Kunena display width?
