I'm writing to let you know that on November 10th a vulnerability in our
forum software allowed a hacker to gain access to the server hosting our
community. We have no evidence of any personal data being stolen (nor do
we store any on our forums!) but as a precautionary measure we are
forcing all users to reset their passwords. The next time you attempt to
log in, please select the "Forgot Your Password?" link below and follow the steps.
