Twitter is a free social networking and micro-blogging service. Users post 140-character messages known as “tweets.”

Users who want to customize their Twitter profiles can launch a Twitter background contest here on 99designs.

You can even Tweet your own contest once it’s launched to make sure all your followers know about your contest - or if you want even more people to see it, why not choose the Twitter Promotion for your contest? For just $99, we’ll Tweet it from our own trusted 99designs Twitter account, so that over 27,000 of our followers will see it!

If you’re already on Twitter, why not follow us @99designs
