Hi there,
I think it would be nice if Scouts can be sent a happy birthday message once a year. This can be an automatic message that Scoutbook sends to the Scout (and/or his/her parents), or it can be a reminder sent to the Den Leader and/or Cubmaster, so that they can send a message. Or maybe they can mention it the next time they see those Scouts.
This is fairly low on the priority list, but I think it needs to go on the list as a nice-to-have.
Regards,
Jacques
