In order to be able to access the chat in Yazak, you need to log on to a Yahoo account that you may create directly in a few minutes from the chat client. When you have your login, you only need to choose a country and a chat and then begin.
Once you are in you may see that Yazak has a style very similiar to the chatrooms of the 90's. Whether this is good or bad, will depend on the user because for sure there is a nostalgice person who will be charmed by it.
Yazak is a very interesting chat service for many reasons. It is a solid alternative to Messenger that has a good community, Microsoft viruses do not affect it and it is an easy to use program.
