The global net system has certainly played an important role in the increase and the following modification of communication dynamics. The term 'online community' has become increasingly popular and refers to a group of people in the online forums who share opinions and information as well as strong feelings of camaraderie, empathy and support (Preece 2005). Message boards have become the easiest way of asking for any information, and anyone can register to participate in an online discussion. The exchange of detailed knowledge, ideas or questions satisfies the users in most discourse domains because such exchange is fast, easy, and free.

Time, money-saving and anonymity guarantee an enjoyable aspect to these interactions
