[kubamaster93]

Long, long ago ...

I wanted to create an e-mail address... My name is Kuba... I used it, but someone had already "kuba".
My friends called me "master", because I was the best in different games.

So, I tried "kubamaster". But again someone had already it.
So I thought that I add my year of birth.

And this is a history of "kubamaster93"...

But I like shorter nickname of kubamaster93 - Km93
