Photo assignment gives you the chance to tell your stories in pictures.

To mark World Aids Day on 1 December we want to see photo essays from readers around the world, portraying what it's like to live with HIV.
You may have HIV or Aids yourself and want to tell your own story.
You may be a care worker, or you may have lost a relative or friend to Aids and want to tell their story using pictures of their life.
It's for you to decide, but we invite you to interpret the brief as widely as you can - don't just think of the obvious.
We will publish the best photo essays on BBC News Online in the run-up to World Aids Day.
Or, if you simply want to send a single shot which captures your experience, email it to us and tell us your name, where you are from, and some information about the photo.
There follows a brief guide and a completed assignment by an Aids doctor in South Africa to help guide you.
Ideally you should aim to take a variety of photographs - it's a good idea to plan the story before you start. A good first photo would be one that introduces the subject to the readers.
Makes sure you take some close-up photos as well as some wider pictures to show the subject's environment but remember to include something in the foreground to add impact.
When you take the picture, remember to look up or down to see what's around you. You might get a better shot if you kneel, or find a position to look down from.
The completed photo essay will have no more than 10 photographs, but you can send us more to choose from.
Make sure you have permission from anyone pictured before submitting the photographs.
Each picture will need a caption.
Who, what, why, where and when is a good place to start when gathering information for the caption, but where possible quotes from those pictured and a description of how you are feeling will help bring the essay to life.
We don't need many words - no more than 80 per picture.
