There's got to be a way to let alliance members know what troops you are requesting when they don't have any of them. They need to know not to send anything they feel like when they can't see any highlighted troop. The problem I'm trying to resolve is getting my portal stuffed with things I don't want, from people who either don't speak the language used in chat... Or don't see the pleas to stop sending wrong stuff!! Put that in the updates hopper and see what your programmers can do.
