I need a script that does two things. First, a user can sign up to my site via a registration form. In that form they can enter their site name, site url as well as their sites RSS feed.
Then, the script would grab one entry from each rss feed that has been submitted to my site and then display that information on the frontpage. The script would grab the Title, Description, URL and image file from the rss feed and display it in a list.
That's the first part. The second part would be that the script would periodically update the rss output list on the frontpage. Every set hour or so, a cron job would run and re-order the list by putting the site's rss feed that sent me the most ammount of traffic to my site at the top of the list.
