Wait a second...do you guys need swapdoodle in order to get swapdoodle notes? If so, that's a pretty lousy system. You should be able to get my notes regardless from your notifications. I figured out that my son wasn't getting my notes because his streetpass isn't activated from the app itself...which needs parental consent. I already have streetpass active via the main system parental controls with my consent so I don't understand this stupid redundancy and now I have to wait for yet another parent code to input so he can get and send notes back to me...this is just doodles we're talking about here, come on.
Also, you know what I hate? Everybody saying they need to ensure you're an adult by paying .50 or a dollar with a credit card...very nice system they got there...can you imagine the money they make from that system alone?
