I am looking to have a system built that is similar to h**p://[url removed, login to view]
There will be some differences to this system but this is the closest description of what needs building that I can provide at this time.
Customer signs up logs in and donates a blog (webform captures wordpress blog user login details and url etc and stores in database)
Customer can then submit a 'post' to be submitted to each blog in network over x amount of days (chosen by user) Post is stored in database and a script posts to the blogs at the user defined rate.
A script is also required to automatically install a specified plugin to each blog in network after customer signup.
