Wikibreak is a great way to let others know that you are away. Some Wikinewsies can be very active and newsoholic and might regularly require temporary breaks to give their mind some rest. Some find it easy to endure, whereas others find the separation agonizing. Often the latter find themselves grasping at any opportunity to go online "just to check what's happening".
Next time you are on break, don't forget to add a Wikibreak template to your user page or talk page.
For general breaks, use {{Wikibreak}} to get:
Wikibreak is taking a short wikibreak and will be back on Wikinews soon. 

If you are busy in real life, use {{Busy}} to get:
When school beckons, use {{At school}} to get:
This user is in school.
This user is taking a wikibreak and may be away or inactive for varying periods of time.
Although they may occasionally be able to do some editing, messages left for them may not be replied to for a while.
They will be back on Wikipedia when school is over.

If you are having exams then it is better to study so, use {{Exams}} to get:
Wikibreak is taking a short wikibreak to get ready for exams and will be back on Wikinews once the exams are over.
Alternatively, you can use {{exams|date}} to specify the date that your exams finish. That will yield: 
Wikibreak is taking a short wikibreak to get ready for exams and will be back on Wikinews once the exams are over on date.
