Does anyone know how to show an article which has a boolen option ticked, so if you had to pick a random article that it about a certain subject to show on the front page.

I wanted to use the <% control %> method but cannot find a tutorial on how to do it,

cbartgu,

The easiest way would be to create a custom method that will return a random article.
Example:

// put this in your Page_Controller
public function RandomArticle(){
	return DataObject::get_one('ArticlePage', 'Option = 1', true, 'RAND()');
}

Where 'ArticlePage' is the name of your Article Page Class and 'Option = 1' would be the WHERE statement.
Then in the Template you could write:

<% control RandomArticle %>
... access members of the ArticlePage here ...
<% end_control %>
