Related Posts Plugin

I'm trying to find a plugin that provides related posts.

I've tried using a few different ones i.e.

http://fairyfish.net/2007/09/12/wordpress-23-related-posts-plugin/

But it doesn't work correctly. It just says no related posts.

Any suggestions?

 

I am selling this wordpress related post plug-in, contact me if interested

 

perhaps this one:
http://wordpress.org/extend/plugins/similar-posts/

 

I am using this one and its working just fine.

 

They are based on different things, some are based on related tags, some are based on related titles, and some related content if it's possible.

 

Ahhhh finally one that worked perfectly.

Thanks!
