BBC Sport uses a selection of social networking tools as an alternative means of covering sport around the globe.
These tools make sharing our - and your - images and stories simple, easy and fast.
Read on to discover more about the tools we use, and see examples of the ways we use them.
FLICKR
Introduction
Flickr allows users to easily upload photos, see other users' photographs, and add tags to photos which describe the contents within the image.
Our first major project using Flickr saw two journalists travel to the 2006 World Cup in a camper van, sending photos back from Germany. We also operated a Flickr group in conjunction with Radio 1, allowing anyone to contribute photos taken at the World Cup.
Since then Flickr has played a part in our coverage of the Rugby World Cup, the Hatton/Mayweather fight, the Beijing Olympics and, thanks to Test Match Special's own account, cricket.
How does it work?
You can view BBC Sport's photos on the Flickr website without having to sign up, but you will need to register if you want to upload your photos and add them to any of BBC Sport's groups.
We are always adding our own photos, taken by reporters, producers and even top athletes, and you can find these on our Flickr homepage, as well as on special feeds in certain parts of the BBC Sport website.
We have also created groups for certain sporting events, where we invite your contributions to sit alongside our photos - which means your pics have the chance of appearing on the BBC Sport website.
If you would like to contribute, once you have signed up, follow Flickr's help guide to find out how to add photos and send them to our groups.
Where is it being used?
You will see links to Flickr photos in various places on the BBC Sport website. Places to look include the golf, cricket and Olympics indexes, plus the Your Game and Sport Relief campaign homepages.

Introduction
BBC Sport first used Twitter at the 2007 Rugby World Cup, where ace reporters Ben Dirs and Tom Fordyce used the innovative messaging service to post short updates alongside their blog from the tournament.
Twitter lets you publish updates the size of a text message - called "tweets" - to the world, telling people where you are and what you are doing. For reporters, Twitter can be very useful when you have something to say but not enough to warrant a full report or blog post. It also comes in handy when you have no access to the internet, since Twitter accepts text messages from your phone too.
The latest Twittering BBC Sport journalist is Paul Fletcher, from Euro 2008 in Austria and Switzerland.
How does it work?
Anyone can get started with Twitter by going to their website and registering for an account. Then you simply fill out a form to send a new update, or alternatively you can set up a mobile device, then send updates from that.
BBC Sport journalists at the Olympics will use mobile phones with GPS (Global Positioning System) technology to send Twitter posts, which will also carry information about where in Beijing our reporters are.
If you like a particular individual's Twitter updates you can subscribe to them, and receive every update they publish. So if one of our Twitter feeds interests you, sign up and add us to your list.
Where is it being used?
Our Twitter updates appear in special bubbles alongside posts on our Rugby World Cup, Euro 2008 and Olympics blogs.
From there you can click through to any individual Twitter account if you would like to subscribe to that feed.

Twitter's updates are also known as "micro-blogging". Jaiku offers a similar service and status updates are also available on Facebook.
