1. The advantage in joining an organization is that an IT professional will expand his/her knowledge, learn more and also share his/her knowledge to others. It is somehow disadvantage if your commitment to that organization is needed and you also must obey rules and regulation of your organization.
2. On my own opinion, an IT professional should be a licensed one or should be certified. It is because being an It professional, a person must be licensed or certified on his/her field of expertise just like other professional. It is also the person's pride or affiliation if he/she is certified to be an IT professional.
3. If ever there is a certification or licensing in IT field maybe the title is registered IT professional.
