Many people get banned and muted mostly because they haven't read the rules of the server. Most people don't even know there's an international sub-forum where they can actually read them.
My suggestion actually belongs to Zhalifa and Dotgirl to whom I say thank you for caring! :) Just as a copyright measure, hehe!
-Make the rules clearly visible on the website. Either stick another button in there clearly stating "Rules of the server" or make them visible on the front page. My guess is this will have a positive effect on the social aspect of the server and it will make players aware that a set of rules exists.
-Show a list of server staff on the website, so players are fully aware who they can call for help if they need it.
-Create a system to identify chat moderators on the chat. Either different color name or a prefix in their name. I suggest this because many times a chat moderator sees something bad(in terms of chat violations) is about to happen on the public chat and he will issue a warning. Many times, this warning is either fully ignored or given a "smart" comeback like "fk off" or "who do you think you are? LOL" etc resulting in even harsher punishment, including harshest one:-insults towards server or administration.
-Create a wishlist thread on the forum where players can input their most desires in terms of WoW, wether it's mounts added to vendors or items to the webstore, this would be a great place to get your wishes known by developers and administrators alike.
-Add a private chat channel for staff members, where Moderators can see and talk to GMs and administrators in cases of emergency or just regular problems, such as exploits. Many times, as a chat moderator, I have witnessed exploits being used and I couldn't contact anyone. I had to go through the regular process of taking pictures+reporting them on the forum. This takes time. Time that could be better used working on other problems. If a mod sees a major infraction being done, a simple message to a GM would solve the issue in less then 2 minutes. I have this relationship with Talvior where I can just /whisper her in case I see someone flying in a BG for example. 30 seconds later, they get banned. Make this system for all Moderators and GMs in a simple, private, chat channel.
