Finally we got cvs login for the drupal.org to put our module in the drupal contributions section. Now facebook like stream module is available at location http://drupal.org/project/facebook_stream
I got cvs login after 11days of applying for the cvs. It is not so easy to get cvs login. I sent request through the http://drupal.org/cvs-application/requirements link. It is must to follow the instructions specified in the above link. I was talking about this in the #drupal IRC channel. Finally got the cvs login.
