It's a moderated public forum, and everyone is entitled to their opinion.
It wouldn't hurt to precede official statements with the words "official club statement" to eliminate doubt.
Just because a person is a volunteer does not make them immune to fair criticism. The moment you post something on a public forum you are open to comment and if you can't take it maybe you'd be better sticking with sycophantic buddies. That's not a comment against the OP just a general observation.
It's been stated before, this is not a club appreciation society but a fans forum. This brings forth a raft of "characters", some strongly opinionated, and when times are bad (no one can deny our finish to last season and start of this have so far been dire) they will quite rightly have their say.
