I would definately let Casey know. What a strange situation all around. I don't remember specifically from signing up at Ravelry, but I know that every vBulletin site I've ever signed up with, I've had to confirm that I was over 13 years of age. If Ravelry doesn't have the same legal agreement, they probably should. I agree that it's not really an appropriate place for a bunch of 3rd graders to be hanging out. And to be honest, I think it's really strange for a teacher to not only be encouraging it, but to be actively assisting them.
Jack, please don't take this the wrong way, but as an adult in today's society, I would never befriend an unknown child over the internet, especially if I were a man. It shouldn't be this way, but unfortunately there are so many ways it can be seen in the wrong light, I personally wouldn't put myself in that situation, regardless of how innocent my intentions were.
It just blows my mind how naive this teacher is, that she would encourage a minor under her care to develop any kind of relationship with an adult stranger over the internet. Does she have no idea how many perverted, twisted people there are out there? This whole thing is very disturbing to me :(
