How to make SMF forum to occupy full-width?

[hhtmp88]

Dear all,

I am a newbie and hope if anyone can give me a hand to solve the captioned problem.

I am using the default template, "rhuk_solarflare_ii", that goes with the Joomla! 1.0.11 Stable installation.

With the exception of SMF forum, I have set to display no modules in the left menu column, it does, but a small box is still displayed and the SMF cannot occupy the full-width of my site. A captured screen of my site can be found from:

Can anyone give me a hand and instructions on how to remove this small box?

Thanks a lot!
