I personally don't care for the +/-
All it takes is for one person to not like somebody clicking - on everything they can for someone, to make that person feel unwanted by the entire community. The childish actions of a small few can ultimatly alienate numerous people and in the name of being fair to all I feel it should not be in effect.
If you dislike someone or something they said, either talk to them as an adult - as we all are or just ignore them. Leave childishness off of this board.
...oddly enough, I see I have a 0% warn status. Surprised me, since I actually did get into it pretty fiercely with someone on here lol. I didn't hide behind a - button to do it though
