As always we remind posters to please follow the rules:

Open discussions are often useful and enlightening. Criticism is acceptable as an important part of public conversations, but we expect everyone to treat others with respect. Experience suggests it is best not to post comments while angry. We reserve the right to delete comments that we think include personal attacks, are disrespectful, threatening, obscene or in other ways objectionable. Anyone who repeatedly violates this policy will be banned from participating in our forums.
