Hi all! In social networks, people spend several hours every day, so they really like to communicate. One of the very first social networks in the world was classmates which allowed people who studied together to communicate. And despite the fact that this social network is paid, they have a large number of users. In this social network, it is quite easy to find all the people with whom you studied but then lost contact. Here you can write messages, send photos, schedule meetings, and more.
