Hosted wordpress integrated with facebook?

Hey all, we have a site at http://www.pissedramblings.com which uses wordpress as its base with a little customisation to the users access amongst other things.

What we want to be able to do is to allow our users to have their posts / all posts show up in a minifeed on facebook.

I’ve seen a lot of posts on how to do this as a memberof wordpress.com, but none of our members will be a member of wordpress.com, they are members of our humble little site.

Does anyone know if theres a tute / prebuilt solution on making our own ‘pissed ramblings feed’?

Any help is much appreciated.
