1) I've started more flame wars than you can track.
2) I act as a "smarter-one". I can remember feeling like I'm the best 15-year-old programmer alive. I've shoved my word's into the place of other's own accomplishments; for example, "I can make a better one."
3) I obsess over things and make the wrong priorities, resulting in very harmful damage to this forum's stature. I've noticed that this forum has been tearing apart ever-since I started acting up.
4) I haven't coped with new-comers, and I haven't really helped many topics either.
