New Delhi, Nov 6 (IANS): The Board of Control for Cricket in India (BCCI) Wednesday launched a campaign on social networking site Twitter that will allow fans worldwide to connect and say thank you to Sachin Tendulkar.

During the ongoing Test series between India and the West Indies, all Twitter users who send an appreciative message for Sachin to the @BCCI handle with the #ThankYouSachin hashtag will instantaneously receive a Tweet from @BCCI with a picture of Sachin, including a personalized message and signature in his handwriting, the BCCI said in a statement.

Since @BCCI announced the integration in a series of Tweets Wednesday morning, thousands of fans have participated, including several cricketers like Yuvraj Singh and Gautam Gambhir, to receive their own personal picture of Sachin.

@BCCI is encouraging its audiences to connect and tweet multiple times - via the web, TV and more - as there are many different images and messages that fans can avail of. The integration will be live, while the Kolkata and Mumbai Tests are being played. The service is supported by Twitter India and Digigraph.

"Twitter has changed the way our fans, here and everywhere, stay connected to our sport and its personalities. We at the BCCI have always believed and invested in the power of mobile, digital and social. On the occasion of Sachin Tendulkar's retirement, we're delighted to work with Twitter and Digigraph and offer our fans this opportunity to thank Sachin and take home a piece of history," said BCCI secretary Sanjay Patel.
