On the pal pad you should be able to respond if your not on
someones friendlist if they have that for their settings. This only
applies if they message you first then you get one message to send
back, if they message you again you will have the same exception.
Well first that's what the Private Messages are for and second
people have the Pal Pad for only friends to reply to not get
annoyed by someone... if what am saying is wrong then I don't
understand what your talking about... So no support am afraid.
I am saying that if they ask you something because of a favor you
did i:e sending a plushie, they will pal pad you saying thanks, and
you might want to say your welcome but you are not on their
friendlist.
kind of like that, Harkness, maybe they can choose if they are able
to respond without adding them, because you might run out of room
on your friendlist and have people who bug you so you can't put it
on friends only
