how to get diary off my screen?

i started a task and finished it but now more pop up asking if i want to do it but i dont want to and cant get the diary to get off my screen? tried logging out but its still there.

 

Go through to the main thing and unpin the task and it should go away or you can cancel I'm fairly sure.

 

walk to 50 wildy from edgeville then walk back then run to lumbride from edgville kill a goblin pick up its bones burry them log in and out and its gone =)

 

thanks
