Talking about age, i believe you wouldn't want to introduce a young and underaged child to the forum here, what will he contribute or even understand, you can start from your own reach and then later when the child is matured enough to know how to live independently then you can introduce him to such community here, as a matter of fact no any child you will bring in here and likes it because it's not like a social media chatting platform or a gaming zone full of enticement, this platform is not created for children but you can learn from hear and teach them till they can comprehend this forum.
