So, here's how it works.
Notice your keyboard.
Type what you would, but in my language.
Do so by pressing the key to the left of the letter it is in english.
If the letter is the very left of the keyboard, do the very right of that line.
You must be using a English (US) QWERTY keyboard!
For example:
Qwkxinw ri vkixjk'bsm $`,
Welcome to blockland, %1.
You must translate what the person above you said, then type your own.
I'll start.

EDIT: I've done too much. I'll leave it to you guys for a bit.
