Youth is a valid excuse for inexperience, not unintelligence. If one holds a disdain for learning and respect, they hold it from the time they first begin to learn until the day they die. It is better to wait to see whether a member's posting style changes over time as they mature and ease into forum life than to condemn them immediately for short posts, though people who have been at forums as long as us can see the telltale signs of a hopeless person immediately. Encouragement is the best thing we can do right now, definitely; we simply watch the newer people progress toward better posting skill, then weed out (not in the sense of banning, but ostracism) those that refuse to take the initiative. It's as simple as that. Prove yourself to be a worthwhile person or face the consequences.
