Yeah it's really hard when you have younger children who are smart enough to read and people are cursing like sailors in chat. May daughters like to watch me play some times, and I don't feel it's right for me to ask those on the server to tone down there language.
Would be nice to simply be able to toggle chat on or off somehow.
This game is great for kids, but there's no way I'm letting my daughters play on a server without some sort of profanity filter or a way to disable chat entirely.
And before you say Single Player Mode, it would be nice if I could build some things with my kids. They love playing and building blocks IRL with me and want a chance @ doing so in Minecraft.
Another incoming suggestion is going to be "Start your own private server". Again, I've already got a lot of time invested on the server I play now so it makes sense to have them there with me.
