Hey everyone. First of all, amazing job on this whole project! I'm glad that it's so successful :D
But I just have a concern. I know that you're trying to avoid DDOS attacks so you only list some of the countries, but I believe that you should at least have a chart or something that lists all the countries that are currently volunteers for the time given. Along with that, you should also show which country shows that country so I can know which country to connect to so I can connect to the country shown on the chart. It might sound confusing but I think that it's a good idea.
