You can't be a real country unless you have a beer and an airline. It helps if you have some kind of a football team, or some nuclear weapons, but at the very least you need a beer.
Maintain and manage site like Laputa involves considerable expenses: e.g for renting a server, purchasing software, books and licenses for images. But especially need hours and hours of work to research, read up (we still going to the library), write and review… the result is available to everyone. For free. We don't care, we have fun. But if you like what we are doing and want to support us, you can offer us a coffee, a beer or a pizza delivery. How can you do this?
