Does anyone know if there are restrictions on programs you can participate in? We are just now learning about all the offerings, like Davidson, Johns Hopkins CYT, SIG, etc. Can you belong to more than one? Since we've not been accepted to any yet, I just don't want to apply to a bunch, if becoming a member of one group prohibits joining others. Obviously, I see it as the more the merrier. But, I wasn't sure what these various groups thought. Anyone know?
