This server should add a group chat plugin. Sometimes I want to talk in private with a big group of people and I don't want people from outside our conversation hearing what we're talking about. Other times, classes get cancelled due to a professor's inactivity and then we end up doing the class in local, but it gets annoying also when people talk in Global, so you can't really focus on what the professor is saying. There's also a chance that you're talking with a bunch of people from a different house, so you can't talk in House chat.
It's basically like when you're in a class and you can't see what people are saying in Global, but you can hear what the professor is saying, etc, etc.
