Currently you do not receive IBO credits on this platform.
With IBOanswers you receive "Points" which are given by asking and answering questions. You awarded additional points for voting the questions and answers up or down. You can also be awarded "Best Answer" if another member feels your answer is the best out of all the other answers given.
Just like any other question and answer board, the object is be helpful and build relationships as well as authority. Points that you earn here can really show off how much you are willing to help others. A 1,000 points put you at an "IBO Guru" level which definitely had drawn attention to you.
