Auto Post On Wordpress From a Particular Feed?

Are there any ways you can automatically post to wordpress blog and the only source is an rss feed? I saw a script that does this but its complicated, I think they call it RSSToBlog. But is there a wordpress plugin that does this? Thanks in advance..

 

try wp-o-matic

 

try that wp-o-matic, but the server i'm using does not seem to be meeting the requirement
