Evidence for intent to sell?

[MonnyKay84]

I live in Colorado. My 15 year old sister has been acting up a lot lately, so when I noticed she left her computer on, I started reading things. I found a conversation between her and another teenager on the topic of drugs, ecstasy and weed, specifically. She asked him to give her ecstasy, he told her that he could get her some, and what I think he meant was he would take her money and buy for her from a dealer, then deliver it to her. When I confronted her with this she claimed she was just joking, but no one said anything about kidding or joking, and the tone of the conversation is very serious. Would a screen capture of this conversation be enough to get either of them in trouble, and how much trouble?
