He is talking about the plugin FeedWordpress: http://wordpress.org/tags/feedwordpress I haven't used it so I can't help you out pipes, but I thought I'd just clear that up.
I've used it before. If you choose the right RSS feeds (ones that show a lot of content) , it can work pretty well. But I suggest that you invest a little more into an auto-post plugin that has more options. I know that one user on here was selling one that posted at different times and took RSS feeds at random.
Apologies Steupz, i should have explained properly. Thanks myp, i ended up installing it last night, it seems decent. Thanks themanbeast9, il look into that.
