As one of the original participants in this buy I've checked back occasionally and been disappointed and troubled - this was started back in 2014 and its now 2017. Still, it seems the whole project was started with honest intentions so it's best to look forward.
I'm not in a position to get involved with the physical shipping of the keyboards, but it's clear that people's addresses have changed and there may no longer be a clear record of who got what.
Given that the original order was for 11k, I estimate that there were something like 60 buyers. With 10 'logistics' volunteers that makes 6 to a person - get in touch with them, figure out what they expect to get, confirm the latest shipping addresses, and act as point for people helping with shipment. Sorting through the paperwork, handling communication and figuring out what needs to happen logistically could certainly contribute to the delay so alleviating just that piece seems worthwhile.
I am more than happy to sort through whatever records exist and get that information ready for anyone else who wants to help.
It sounds like original buyers may not get what they expected. Clearly its time to ship whatever is ready and call it a day. With a general sense of what is missing from the current inventory "breaking the bad news" can happen and we can all move forward to wrap this up.
Finally, with the various problems with the project along the way there may no longer be any funds remaining for the actual shipping. I can only speak for myself here, but I'd be more than happy to kick in for priority shipping for my keyboard (I'm in the US) - just bubble wrap it, toss whatever is ready from my order (plates, board, or whatever) in the premade box, and ship. Hopefully most participants are in the US and this is a valid option for many of us. I realize this is a big ask for everyone but at least for those reading, consider the possibility that you have may to spend a bit more, and may get less - its better than nothing.
Thanks to others who have posted here.
For mkawa, I know you'll be happier than all of us combined to get this wrapped up. Being able to ask for help is a skill so work on it now: get on your email, get back to people promptly. If some more funds for shipping and so on are needed just be direct about it. Projects don't go perfectly, thats no reason to give up. Hope we can all make something happen soon.
