In the modern world, people use different media to communicate with each other. For example, we have Facebook, WhatsApp, WeChat, and many other social networks. But in the old days, before the Internet, people used to talk to each other in a different way: by writing a letter or a message on a piece of paper, and sending it by hand or via a mail service. 

Now we have the Internet and a lot of new technologies. So why do we need this old method? The answer is simple: we don't. We don't need to use the Internet to send messages to each other. We can do that with Sotla. This is a new messaging app that allows you to send and receive messages in a simple way.
