I probably wouldn't use it. I know from experience that when you are in a chat of more than five people it is really hard to speak to a certain friend as there are constant questions and comments. Personally I just skype with my friends who I am building Ferocraft with, as we are all friends in real life. I'm not stopping you guys though, it's a really good idea, and a much quicker way to communicate, especially in things like the survival games. The one question I have is: How would you control swearing issues?
