  • Ban policy update:

    Due to the actions of numerous repeat trolls, bans will now only be lifted on 4 month intervals, rather than 1 week intervals. Troll bans are set to be lifted on 12/15/07.

    If you are worried that your comment will result in a ban, search through the already posted comments and see what caused others to be banned. Do not repeat their mistakes. If you exercise a minimal amount of tact, you will find that we are more than accommodating to both questions and valid criticisms.
