Chat activation?

I kinda removed my chat from the game by aciddent. Anyone has any idea how to add it back?

How you remove it? can you post screen?

Well, I'm not sure how I removed it, I initially removed the top chatbox and was clicking around below the second one trying to put it back and ended up removing both. There goes the screen:

Same thing happened to me a few days ago. Since I didn't find any answer anywhere I'll post how I managed to get the chat back.
You accidentally pressed a button that pops the chat out of the game, to its own window.
The chat is now located in a smaller window attached to the right side of the game, as you can see in this screen shot:

Clic the button marked in red to make the chat go back to the main window. That's the same button you pressed to pop it out before.

Hope, this post will be useful to everybody who had the same issue.
See ya!
