RSS aggregation

Hi,

A few months ago I experimented with a plugin that would let me specify an RSS-feed and the plugin would then monitor that feed and import whatever was in it as wordpress posts. There was also options for including the new posts in the feed, or not.

I can’t seem to find it now, no matter how much i search. Anyone know what I’m talking about, and would be willing to point me in the right direction. Help would be most appreciated.
