Page to be a blog

Yep, you can have different pages as different categories.

So you could have a soccer category, football, cricket etc.

You would just link to them like normal pages.

How do I do this?

Just make a category in the WordPress dashboard and assign posts to it.

Depending on the permalink settings you are using changes what the url will be.

An example is on my site: https://wpkickstart.com/category/screencasts/

That is a category.

And since you are using WP 3.0, you can use the menu generator to easily include the appropriate categories in your navigation

As long as the theme is compatible ??

I want blogs to appear in the ‘about us’ page only and different blogs on the home page.
