What do you think about to contact geocaching community? I sent an email to a french community and they are interested to post an article about it. We all need to promote checkcoin.
Just a thought: I hope we will be able to hide the checkpoint's reward!
Excellent idea, get as many people onboard as you can. First I thought I'd wait until the software is fully developed, but now would be a good time for people to join our ranks. The community is growing every day, which is a very good sign.
