That's rude. I hope someday when you ask someone a question they stomp on you to. You should never expect anyone should have the same level of level of skills as you. Some people are just starting out and others know just a bought enough to be dangerous to them selves. but that's no reason to be a jerk a bought it. You need to grow up and stop belting people so you can feel better a bought your self. Don't give a long drawn out synthetic explanation of the problem, only to tell the poor guy what he already knows. Don't give out tiny little crumbs designed to be thought provoking. Give the poor guy the hole cookie, the real fix. When just give out crumbs or re explaining his problem in a more scientific way, it only shows that you really have no idea on how to fix the problem in the first place. Do you really need to put others down to make your self fell better? Just grow up.
