If there was a club rep on the site, I'd tone down my comments for fear they'd get back to the players or club. It's not a bad idea having a club rep to answer questions and disseminate information.There is a couple of the media team guys on here but there involvement is more to get feeback on the website, facebook, twitter, live game chats etc. rather than actually communicating with the club.
I believe Richmond has an official club username that communicates with them on their board, might be worth a look there.
