Going back on topic, 3 females: Idina, Tracie and Rosario. Tracie does have the solo in SoL, and Rosario is not as vocally strong as her other female costars, thus the boost of Idina's vocals? Makes sense to me. I agree completely with that. Plus, Idina's just got a strong voice. She's going to stand out. And if she does, good for her (as long as it's not excessive and takes away from the songs).
About the other topic on this thread, I am very shy in person, until I get to know someone, and I know that if I had fans like that, I would be totally freaked out. She doesn't have to sign. I'm surprised she makes it the times she does. That being said, I'm going to SWIWS on the 20th, and will kill someone if there are screaming teens there. Not because of the signing, but because of the show. And if she signs after, great. If not, fine also.
