If you would like to try it out for yourself, download it from Launchpad and put it on your web server. Yes, you need a web server and PHP. Currently it runs on my private testing server, and you can do the same; but I'd really appreciate it if someone would put it on a publicly accessible server so others can use it. If you get it running, please tell me so I can post the link here for others to use.
So head on over to the project page on Launchpad and download it if you can. You can get the development version through Bazaar if you know how, but it may actually be easier just to download each of the files individually from here. After downloading you'll need to add a file with your API key. If you're familiar with PHP you can probably figure out what to do despite the lack of any decent documentation in the script. If you need help, contact me. If you know exactly what you're doing and want to improve the script or its crappy documentation, also contact me. I will gladly commit any improvements under the assumption that you're probably a better a better programmer than I am.
If you get it running, need help getting it running, want to contribute to development, or just want to chat, just send me a message. I'll try to respond in whatever manner is appropriate.
