So many people ask about this every day! Check ou ta quick google search - I found http://magpierss.sourceforge.net/ . I'm not sure if it's good or what you're looking for, but hey.
do yu just want to publish the feed, or do you want to go off and grab the full article text for each article and publish those?
then you need some sort of scraper. And some way to spin it to make it unique first. otherwise it's a complete and utter waste of diskspace, bandwidth, and time.
It doesn't seem to be making the content unique. When I look at the demo site, I can find the first article (the 'Miss Universe' one) in hundreds of places. Unless of course, you wrote the article yourself, in which case it's hardly an 'autoblog', is it. Parsi, yes you can run Wordpress locally. You'll need a local PHP and MySQL installation. Comes as standard on a Mac, btw.
Thanks a lot boss. I shall install `easyphp' in a few days. I guess that should be sufficient or anything else is required?
