Some suggestions i have to the serverbrowser would be if a host, ingame can set extra information to the server. For example, you could have something like "looking for players", "willing to teach", "experienced players only" etc. I'd think that could be kind of useful in situations where you might want to learn a new game, then you can join one of the servers with the "willing to teach" tag on it, or if you don't want to teach someone every time you want to play a game. And the "looking for players" tag should be self explanatory. I hope you like this suggestion!
