a while back we started developing on "Rugatu Q&A"
with the ideal to build the most complete service that would have bitcoin at it's core. We based our code on the well known OSQA opensource platform so that our users can enjoy features they're already familiar with, and use bitcoin rewards on their questions if they wanted to.
Now we reached the testing phase so we would love to hear your thoughts and opinions on it. For the purpose we currently use "testnet coins", you can get them for free at the "Testnet Faucet"
or you can post in this thread and we will make sure you get some coins to test with.
Come visit us at rugatu.com
EDIT: We will be giving free real bitcoins, once we launch, to anyone who spent some time asking or giving us feedback on the service.
