I have heard that there is a community over the internet wherein people from different parts of the world interact with each other, and whenever they travel to different countries they contact the person living in the visiting country and stay with them for free.
For. E.g If I am a member of such a group, whenever someone from outside India (like, US, Africa, Europe etc.) wants to come to my city, then he or she will contact me, if I am OK with them I will allow them to stay at my place for free. Same way if I want to travel abroad I will contact someone living their.
This helps to get to know people, cultures and tradidtions across the world, I know such sites exist and would like to be a part of them, does anyone know about it?
