My Son Loves His New Computer

My son is thirteen and has just received his first computer.  This is such an exciting time, for he is like a sponge wanting to learn everything possible on the computer.  To protect him from learning inappropriate content, I put a nanny on the computer, then told him he could Find great info by doing simple online searches.  However, I wanted him to learn things that would benefit him and enhance his learning process for at home and in school.  My son now is a very in formed teenage boy who is an eager learner, and loves acquiring new knowledge all the time.
