I use whatsapp to keep in touch with all of my family members who live abroad. Some of them aren't very tech savvy and they still manage to utilize whatsapp to its full potential so that is also a huge plus.
Bought a game here today. It is kinda similiar to kinguin, but is not as popular and has a confusing webpage layout. When it comes to service, it works as intended. I've activated my key without any problems.
