Yea, about the devcommands and such I was aware. But I just want to play creative-mode with my friends. That's basically what I'm asking :D

So, for example. If my friend hosts the game which he is and he tells me and the other group members to use a 'trainer/mod' or something. Is this allowed? Like, anti-cheat stuff?

Since we want to start a huge project with creative-mode, that's why I'm asking.
