Page of Posts

Hi Guys,

I’m trying to create a website with wordpress (obviously!).
and i’ve set my homepage to be a default page (home) in the reading settings.

I was just wondering how i would set a page of posts in a specific category…I know in the Reading Settings you can specify a new page for the posts to go on, but thats all the posts (i want to split my blog into two blogs (using top level categories) and wondering how to do it…

Hope that makes sense?

Thanks,
Jon
