Last night, I went to a women's conference at our church, featuring Natalie Grant and Charlotte Gambill. I have never heard Charlotte speak. It was quite a wonderful experience, learning a new view on being in "the middle".
I got the bracelet for supporting Natalie's ministry called Abolition International, which targets human trafficking. I can tell you it is much more prominent than we would like to believe.
I agree with Penelope and Al! There seems to be many other organizations appearing that are trying to bring this terrible activity to the publics eye. One of my favorite Christian songs is by her: http://www.youtube.com/watch?v=IuuLBPOYcI8&feature=kp
@skipt07 I have to confess that, though I know Natalie Grant, I don't know many songs of hers. I don't know the one you linked to. I do like her song, "Hurricane" and she sang it last night. Both ladies did an outstanding job. I heard they were simulcasting the event last night and there were even more computers set up than we normally have.
