Taarifa a project from the London Water Hackathon is now a fully fledged open source project. Currently hosting and the like is being set-up, though taarifa.org. Taarifa is a platform for reporting and workflow of community problems, based from the Ushahidi source code. Currently we’re targeting the Web and Android platforms, but I’m sure we’ll be considering iOS soon.
We’re currently looking for volunteers from any background, be it coding, documenting or design. To get involved ‘check-out’ our code on github: https://github.com/taarifa/. There is also a mailing list through Google Groups: https://groups.google.com/forum/#!forum/taarifa-dev.
Eventually we will be having nightly builds from the bleeding edge being implemented on beta.taarifa.org. Until then please check-out the code!
