When using the Streetpass feature of Mii Plaza, you walk around and gather 'friends', which shows up as a notification (Green LED light on the 3DS, and a green dot on the game icon).
Can I safely ignore these notifications for an extended period of time, without losing the new friends they bring into the Mii Plaza? (I'm getting sick of watching all my heroes turn back in Streetpass Quest, as I'm waiting on someone with White Magic to light up a room). I'm thinking of leaving it from 2 to about 5 days.
