How can I delete "friends" who will not trade gems with me on Dragonvale? Game Center only allows this for multi-game players, it seems.
How can I delete "friends" who refuse to trade gems with me on Dragonvale? Game Center seems to allow deletions only if you are playing multiple games. I'm forced to give gems to those who haven't given me gems for the six months I've played, before I can give to my three reliable friends again.
Thanks.
