Single post in reminder to use a new shiny charm

It could just be a toggle on/off so that individual players can decide for themselves if they want the reminder, any time regardless of whether or not they own the box. Same way the Albino Radar notification works, or those of the Lab, Daycare, etc. (probably easier to code too) If someone who owns a box lends/rents it to someone else and forgets to change the notification settings... well too bad I guess? Support.
