LJ: (or anyone) If you get a fellowship invite from any person whose fellowship you do not wish to join, just ignore it or delete it, then they can not re-invite you. If you decline the invite, they can :o)
(hide) If you want to play a game with an opponent of a similar level, you can define a required BKR range for a new game invitation. Then nobody with a BKR outside this range will be able to see/accept it. (Katechka) (show all tips)
