And I also agree that nicholas acts unnecessarily shitty and immature himself, he does provide some level of knowledge that has come in handy to many of us at one time or another.
If he wants to act that way, let himself give himself a heart attack for not dealing better with whatever his anger came from, no reason it has to bother anyoen else. But youll find that he does have quite a few helpful posts on top of all his drivel.
