Who is running
http://pay.withfedoraco.in ?
Is that service abondened? I see there several old links (old thread, price udpates via coinedup). If this is still under development, I can give some suggestion how to improve your service so that it gets more probable to get used by more merchants.
I don't know who runs it, but they are active. They will be helping with my site soon to sell goods for fedoracoins. I got in contact with them through this email address.
contact-us@pay.withfedoraco.in They responded very quickly. They are working on
http://worldof.tips/ right now.
