One of the best tools on the forums is the ignore list

You never have to read what someone you put on this list writes.
You can read their posts if you want, but that's your choice.
It works... and you'll particularly enjoy when someone you have on your ignore list posts on a your thread. Kinda like turning your back on someone you don't like and walking off...while they are talking. Very disrespectul is my best decription of the action.
Enjoy
