Was about to say I think you need to be 13+ to play, but looking over the PL ToS and then the forum ToS, I think that only applies to the forums.

Anyway, change the quickchat stuff to different things that you'd end up saying? Like yeah, nope, gotta go, etc. and only let them say that? Add a few more slots maybe? I don't support an entire mute/can't see other's chat. Too severe IMO.

RS did a quickchat system that worked out pretty well for 13 and under people, is that what you're suggesting?
