HOW DO I DO SOMETHING ON THIS WEBSITE CAN I JUST CHAT?

To play singleplayer games (first of which is tutorial) you click on "Single-Player" and under that you click "Play," then click on the level you want to play and the game will start.

To join a multiplayer game, go to "Multi-Player" and "Open Games." Then you can click on one of those games to see what it is and click join to join. If you have any questions you can ask in the in-game chat.

If you can't figure that out on your own, then I wonder how you were able to get here in the first place.

start by turning capslock off :P

lol, he's clearly just trolling

When you're new to WZ. you get greeted with a big Play button that takes you to SP.
Since he managed to find the Global Chat, it means he must know how to open a menu, read text and click, which is more than enough to be able to play a game of some sorts.
