I sometimes want to change my armatar to the blank one, like when I'm away or not online. Would you also like to be able to change your armatar to the blank one?
Haha, yeah... making it possible to do so whenever you want would so defeat the purpose of being able to have the blank armatar.
And if you want to switch your Armatar to an "offline" armatar what if someone doesn't have very much time to go online, you won't have a good chance to see their Armatar.
hrrm, well maybe you should say that you cannot switch back when you are choosing an armatar, 'cause that will at least make people acknowledge it... personally, I want it, but not only when I'm offline.
