Anyone know when the next challenge will be and if it will be random invites like the last one? I want to do it but haven't gotten invited. I'm over 13 so don't think that is the issue (I know I heard some people complaining that if you weren't old enough you couldn't do it.) I hope I get invited soon because things like this are really motivating to me.
