519203 Wordpress Plugin - Blog Auto Poster

I have a Wordpress plugin that automatically posts to these blogs: Wordpress, TypePad, Blogger, Live Journal, Multiply, Xanga and Posterous. Unfortunately, most of these blogs no longer work with the plugin. However, the four best blogs do continue to work and it is these four: Wordpress, Blogger, Posterous and Tumblr that I want a modified version of this plugin created for. Basically the plugin posts to these blogs using Cron jobs and RSS feeds. I need the modified plugin to do the same to these four blogs but I want to allow for more connections to each blog. The current plugin posts to one of each of 7 blogs based on the input settings. I need the new plugin to post to five of each of the four blogs. Example: 5 Wordpress, 5 Blogger, 5 Posterous and 5 Tumblr for a total of 20 separate blogs. I have attached the PDF instructions for the original plugin and the plugin itself.
