A mediator is like a middle man, say two people get into a stupid fight, they bring someone in (a mediator) to let the two sort things out and keeping things resonable and civil. Not a bad idea, hopefully things won't get to the point where we need any, but i personally don't think officially recognising anyone as a mediator is neccessary. If things happen, there are enough senior members around to hopefully step in and settle things down anyway. To me a moderator is to keep things on the board running smooth, now even though this board is a big part of the club, i think there's a lot more too it and mods aren't always gunna be able or suitable to mediate between people, either in person or online.
I think we just have to take things as they come, and hope everyone is mature enough to sort things out. I havn't seen any real arguements on here yet that have gotten out of hand and think we keep this trend going.
