How to Show the Top Stories on Home Page

[fpsystems]

I have setup a Pligg site using the latest version of Pligg. I thought the home page should automatically display the Top stories - in descending order of the highest votes. However, I see it only displays the Published stories - and it is not sorted in descending order of votes. How do I do this ?

Thanks

What I want effectively is to make the http://mysitename/alltime (which is the URL for the all time top stories) to be the default home page for my website. How can this be done?

Thanks

Anyone with any ideas on how to do this ?
