The development of the project that raddle is on was discontinued. Change and addition requests will not be implemented until someone starts working on it again.
The codebase is in PHP and the Symfony framework, if someone thinks they can take over maintaining and developing the project please don't hesitate to fork it. There are people that may contribute one day in an active fork.

I have some experience with PHP-- I'll look over the code-base sometime. Maybe I'll be able to help a bit, or learn to.
