Ya, I didn't see any "Alters are JUSt ego states but developed more" either. Unless you count Sun Rises diffanition, I sort of thought that might have being what it was trying to say...
Look, sorry if I screwed up AGAIN...
But Peg, if Alters were just Ego States, as people have wrote, ego States don't really take you over very much, = DID does, Ego states feel like you I guess mostly = DID doesn't feel like you, Ego States more or less talk in 3ed person = DID can talk for themselves.
Ya, I don't think DID is JUST another form of ego States.

. (If anyone wants my opinion.)
