A Conference and two different options!!!!

So...BIG news, I had a conference call with AFS XD!!! It was really cool I really liked it! I was on the phone with a AFS volenteer and around 34 other people interested in AFS, While she was talking we were on a thing called Webanar and we could see the stuff she was doing. So she was on a powerpoint presentation and was explaining everything, History, cost, how to apply, stuff like that it was really cool. She was able to mute and unmute me to talk and unmute others anyway I was the youngest on the conference, But I was really happy and excited. so I didnt care.:D Anyway I'm trying to choose wheather or not to stick with AFS or go with YFU, so I'm really confusedD:
