There are only two elements to this argument as far as I am concerned:
1. This is effectively a chat room on a pay-to-view web site on the bloody
internet so IMHO the only 'out of order' stuff is personal abuse (which would have to be serious as opposed to just name-calling), physical threats or something unacceptably illegal. Other than that, freedom of speech should be the order of the day - and as people have said, I've yet to see anything get out of hand.
2. BUT and its a big BUT, whether its for the sake of Bats server revenue, or our personal/joint reputations (I use my moniker on other forums), we should ensure that we act and speak like proper grown-ups. Just try googling your username and see what pops up......
