Incase somebody responds to my pm during the World Championship, telling me that they can't do it, I need proof to get a bye.

Plz tell me how.

Open the pm, press "Print screen" key on your keyboard. Then go to microsoft paint or any other graphical software and press "ctrl + v". The printed screen will be pasted as an image. You can then save it (file -> save) and upload it to www.imgur.com.

I can't find the button for "Print screen"

if u got laptop do this :-
FN+PRINT SCREEN (PRTSC or PRTSCN)
if u was in the pc do this :-
Print screen/SysRq

I tried that, it didn't work.
I have an ASUS laptop, btw.

Just download gyazo from http://gyazo.com/, install it, run it and draw a rectangle over the part of the screen you want to have in your screenshot. A new browser tab will open with your screenshot ready.

Ok thanks

Alternately you could use te snipping tool. There are options for full screen cuts.
