Winsock BlackPlanet GuestBook Poster

I need a winsock guestbook poster for www.blackplanet.com. This bot needs to load a list of accounts from a text file with this format: username:password as well as load a list of names from a text file that it will be posting to. Also this bot needs to log the names of people it already posted to so it will not post to the same person's guestbook more than once. This bot also needs to be able to support different messages when posting, I need it to randomly choose a message that I add when it's posting. I also need for it to let me enter the amount of postings to do per account. Proxy support is NOT needed.
