How to create contact or admin@yoursite

Hello
Due to some problems www.baratgameworld.blogspot.com is not available now. So I will post here temporarily.
All may have seen this on big sites such as adsense for example:admin@adsense.com
Here is the procedure how to do it.
Go to google.com/a
It will ask your domain name but it will not accept .blogspot.com domain.
So go to dot.tk and create a domain name.
For example mine is www.baratworld.tk(some prob now)
So go and enter your tk address without www It shown in the picture below:






















After it you must activate the email feature there that's all comment, subscribe, and share please
