To be honest, Grimsby Town don't play football anywhere these days.
I don't see the point they're trying to make. Are they saying that only the fans who were either there whilst Newcastle were in the lower leagues, or who pay an interest in lower league football have the right to comment?
See, I know plenty about lower league football, but I don't go to SJP, and I only get to about 5 or 6 away games during the season. I don't feel I have much right to comment on the team at all, unless it's during an argument with LeazesNE5beermonster
