Please ... no.
(1) We already have a tough enough time with posting standards.
(2) Sports can be reasonably covered in other fora: Religion, Biology & Genetics, Human Science, Science & Society, General Science & Technology, EM&J, Politics, History, Economics, Art & Culture, and Free Thoughts--if we need the box scores, there's always Sportscenter.
The "daily chatter" of sports is even more potentially detrimental to our community than the "daily chatter" of politics and religion. I once heard sports radio in Seattle spend two hours arguing about a fistfight in NASCAR. By the end, the hosts were mocking a guy for spending his evening watching four hours of videotaped car racing. (In the United States, just as a reminder, auto racing is best described by a classic bumper sticker I used to see around Spanaway Speedway: Go fast ... turn left.) A seventy year-old woman called in to harangue the hosts about civil rights; their bashing of NASCAR and its fans was tantamount to the plight of dark skin in America--that's right, she compared a joke about NASCAR to racism.
I hate sports radio. I despise sports bars. Please, please ... no on the Sports Forum. I just spent a year without ESPN and FSN droning in my ear all night every night. The world almost seems normal again, but it's a long road to recovery.
A Sports Forum ... oh, please, no.
