This is third part of our series on how to create a question and answer website in Drupal. In this tutorial, we would be looking at how we can allow members of the community tag questions they have asked. To achieve this, we would be using the community tags module. The community tags module allows members of community site to tag contents and also track who tagged what and when. In this tutorial we created a vocabulary called tags, and created a new field on the question content type with term refernce using the tags vocabulary we created. Once that was done we then enabled community tagging on the question content type.
