You probably came to check out Vote-O-Matic, a script that was originally written by Rasmus Lerdorf (heyhey!), then extended by Aubin Paul and then again extended by me. I put my modifications under the GPL (I had no choice anyway, since Aubin did that too) so you can do with it what you want, as long as you stick to the rules.
Well, this is still a little bit beta, so use it at your own risk. I don't know of any bugs, but I only tested it on 2 machines so if you find something: let me know! The code is a mess, so better don't look at it since you might be shocked a lot. ;-)
There is no live sample of the admin-section since that would bring up some security-issues, but under "screenshots", you can find the HTML-page to see how it looks like. That's it for now, check out the other pages for more information.
