How do I set a specific style as the forum default?

[Dunc]

I currently have 2 styles on my forum, the normal vB style and a style I downloaded off this site (Silver & Red by Hellcat, very good :0). I want to make the silver and red one the forum default, because the plain vB style appears to be the default at the moment. How would I go about making the silver and red style my forum's default style?

vBOptions > Style & Language Settings > Default Style

Set the style that you wish to use as default here
